DATA SHEET V01
4. Interface
The HX8347-I supports two-type interface group: Command-Parameter interface
group, Register-Content interface group.
This manual description focuses on Register-Content interface group. About the
Command-Parameter interface mode, please refer to the HX8347-I (N) datasheet for
detail.
In Register-Content interface group (IFSEL = L), the HX8347-I has a system
interface circuit for register command/GRAM data transferring, and a RGB interface
circuit for display data transferring during animated display. The system interface
circuit uses data bus pins (DB17-0). Since the data bus pins (DB17-0) can be used as
input in RGB interface circuit, the HX8347-I shows animated display with less wiring.
System interface can be used to access internal command and internal 18-bit/pixel
GRAM. The RGB interface is only used to access display data. Please make sure that
in RGB interface mode, the input display data is not written to GRAM and is displayed
directly.

4.1 System interface circuit

The system interface circuit in HX8347-I supports, 18-/16-/9-/8-bit bus width parallel
bus system interface for I80 series CPU, and 4-/3-wire serial bus system interface for
serial data input. When NCS = L, the parallel and serial bus system interface of the
HX8347-I become active and data transfer through the interface circuit is available.
The DNC_SCL pin specifies whether the system interface circuit access is to the
register command or to the display data RAM. The input bus format of system
interface circuit is selected by external pins setting. For selecting the input bus format,
please refer to Table 4.1.

Table 4-1: Input bus format selection of system interface circuit
It has an Index Register (IR) in HX8347-I to store index data of internal control
register and GRAM. Therefore, the IR can be written with the index pointer of the
control register through data bus by setting DNC_SCL=0. Then the command or
GRAM data can be written to register at which that index pointer pointed by setting
DNC_SCL=1.
Furthermore, there are two 18-bit bus control registers used to temporarily store the
data written to or read from the GRAM. When the data is written into the GRAM from
the MPU, it is first written into the write-data latch and then automatically written into
the GRAM by internal operation. Data is read through the read-data latch when
reading from the GRAM. Therefore, the first read data operation is invalid and the
following read data operations are valid.

DATA SHEET V01
4.1.3 Serial bus system interface

The HX8347-I supports two kinds of serial bus interface in register-content mode by
setting external pins IM3, IM2, IM1 pins to 010 3-wire serial interface I, and IM3,IM2,
IM1 pins to 011 4-wire serial interface I. The serial bus system interface I mode is
enabled through the chip select line (NCS), and it is accessed via a control consisting of
the serial input data (SDA), and the serial transfer clock signal (NWR_SCL).
The external setting IM3, IM2, IM1 pins to 110 3-wire serial interface II and and
IM3,IM2, IM1 pins to 111 4-wire serial interface II. The serial bus system interface I
mode is enabled through the chip select line (NCS), and it is accessed via a control
consisting of the serial input data (SDI) output data (SDO), and the serial transfer clock
signal (NWR_SCL).
4.1.3.1 3-wire serial interface
As the chip select signal (NCS) goes low, the start byte needs to be transferred first.
The start byte is made up of 6-bit bus device identification code; register select (RS) bit
and read/write operation (RW) bit. The five upper bits of 6-bit bus device identification
code must be set to 01110, and the least significant bit of the identification code must
be set as the external pin IM0 input as ID.
The seventh bit (RS) of the start byte determines internal index register or register,
GRAM accessing. RS must be set to 0 when writing data to the index register or
reading the status and it must be set to 1 when writing or reading a command or
GRAM data. The read or write operation is selected by the eighth bit (RW) of the start
byte. The data is written to the chip when R/W = 0, and read from chip when RW = 1.

4.1.3.2 4-wire serial interface

4-pin serial case, data packet contains just transmission byte and control bit DNC is
transferred by DNC pin. If DNC is low, the transmission byte is command byte. If DNC is
high, the transmission byte is stored to index register or GRAM. The MSB is transmitted
first. The serial interface is initialized when NCS is high. In this state, NWR_SCL clock
pulse or SDA data have no effect. A falling edge on NCS enables the serial interface
and indicates the start of data transmission.

4.2 RGB Interface

The HX8347-I uses RCM [1:0] =10 or 11 Software setting to select RGB interface.
After Power on Sequence, the RGB interface is activated. When RCM [1:0] =10 use
VSYNC, HSYNC, DE, DOTCLK, DB17-0 parallel lines for the RGB interface (RGB
mode 1). When RCM [1:0] =11 use VSYNC, HSYNC, DOTCLK, DB17-0 parallel lines
for the RGB interface (RGB mode 2)
Pixel clock (DOTCLK) must be running all the time without stopping and it is used to
entering VSYNC, HSYNC, DE and DB17-0 lines states when there is a rising edge of
the DOTCLK.
In RGB interface mode 1, the valid display data is inputted in pixel unit via DB17-0
according to the high-level(H) of DE signal, and display operations are executed in
synchronization with the frame synchronizing signal (VSYNC), line synchronizing signal
(HSYNC) and pixel clock (DOTCLK). In RGB interface mode 2, the valid display data is
inputted in pixel unit via DB17-0 according to the HBP setting of HSYNC signal, and the
VBP setting of VSYNC. In these two RGB interface modes, the input display data is not
written to GRAM and is displayed directly.
Vertical synchronization (VSYNC) signal is used to tell when there a new frame of the
display is received , and this is negative (-, 0, low) active. Horizontal synchronization
signal (HSYNC) is used to tell when a new line of the frame is received, and this is
negative (-, 0, low) active. Data enable (DE) is used to tell when RGB information is
received that should be transferred on the display, and this is positive (+, 1, high)
active. DB17-0 are used to tell what the information of the image is, that is transferred
on the display when DE=H.
The pixel clock cycle is described in the following figure.

The image information is correct on the display when the timings are in range on the
interface. However, the image information will be incorrect on the display, when timings
are out of the range on the RGB interface and the correct image information will be
displayed automatically (by the display module) on the next frame (vertical sync.), when
there is returned from out of the range to in range RGB interface timings.

There are 2 kinds of RGB mode which is selected by RCM1 & RCM0 hardware pins.
In RGB Mode 1 (RCM1, RCM0 = 10), writing data to display is done by DOTCLK and
Video Data Bus (DB [17:0]), when DE is high state. The external synchronization
signals (DOTCLK, VS and HS) are used for internal display signals. So, controller (host)
must always transfer DOTCLK, VS, HS and DE signals to driver.
In RGB Mode 2 (RCM1, RCM0 = 11), blanking porch setting of VS and HS signals are
defined by R33h and R34h command. DE pin is not used.

5.1 Display data GRAM mapping
The display data RAM stores display dots and consists of 1,382,400 bits (240x18x320
bits). There is no restriction on access to the RAM even when the display data on the
same address is loaded to DAC. There will be no abnormal visible effect on the
display when there is a simultaneous Panel Read and Interface Read or Write to the
same location of the Frame Memory.
Every pixel (18-bit) data in GRAM is located by a (Page, Column) address (Y, X). By
specifying the arbitrary window address SC, EC bits and SP, EP bits, it is possible to
access the GRAM by setting RAMWR or RAMRD commands from start positions of
the window address.

5.2 Address Counter (AC) of GRAM

The HX8347-I contains an address counter (AC) which assigns address for
writing/reading pixel data to/from GRAM. The address pointers set the position of
GRAM. Every time when a pixel data is written into the GRAM, the X address or Y
address of AC will be automatically increased by 1 (or decreased by 1), which is
decided by the register (MV, MX and MY bits) setting.
To simplify the address control of GRAM access, the window address function allows
for writing data only to a window area of GRAM specified by registers. After data
being written to the GRAM, the AC will be increased or decreased within setting
window address-range which is specified by the (start: SC, end: EC) and the (start:
SP, end: EP). Therefore, the data can be written consecutively without thinking a data
wrap by those bit function.

5.3 GRAM to display address mapping

By setting the SS_Panel, the relation between the source output channel and the
GRAM address can be changed as reverse display. By setting the GS_Panel , the
relation between the gate output channel and the GRAM address can be changed as
reverse display. By setting the BGR_Panel, the relation between the source output
channel and the <R>, <G>, <B> dot allocation can be reversed for different LCD color
filter arrangement. Table 5.5, Table 5.6 and Table 5.7 show relations among the
GRAM data allocation, the source output channel, and the R, G, B dot allocation.

5.4 Tearing effect output line

The Tearing Effect output line supplies to the MPU a Panel synchronization signal.
This signal can be enabled or disabled by the Tearing Effect Line Off & On commands.
The mode of the Tearing Effect signal is defined by the parameter of the Tearing
Effect Line On command. The signal can be used by the MPU to synchronize Frame
Memory Writing when displaying video images.
Tearing effect function is not supported for RGB interface (RCM[1:0]=1x).
5.4.1 Tearing effect line modes
Mode 1, The Tearing Effect Output signal consists of V-Blanking Information only:
tVdh= The LCD display is not updated from the Frame Memory
tvdl = The LCD display is updated from the Frame Memory (except Invisible Line see below)
Figure 5-17: TE mode 1 output
Under Mode1, the TE output timing will be defined by TSEL[15:0] setting.

Ex:
1. TSEL[15:0]=0, then TE signal will output after last Line finished.
2. TSEL[15:0]=2, then TE signal will output at second Line start.

5.6 Source driver

The HX8347-I contains a 720 channels of source driver (S1~S720) which is used for
driving the source line of TFT LCD panel. The source driver converts the digital data
from GRAM into the analog voltage for 720 channels and generates corresponding
gray scale voltage output, which can realize a 262K colors display simultaneously.
Since the output circuit of this source driver incorporates an operational amplifier, a
positive and a negative voltage can be alternately outputted from each channel.
5.7 Gate driver
The HX8347-I contains a 320 gate channels of gate driver (G1~G320) which is used for
driving the gate. The gate driver level is VGH when scan some line, VGL the other lines.

Gamma-characteristics adjustment registers

This HX8347-I has register groups for specifying a series grayscale voltage that
meets the Gamma-characteristics for the LCD panel used. These registers are
divided into two groups, which correspond to the gradient, amplitude, and macro
adjustment of the voltage for the grayscale characteristics. The polarity of each
register can be specified independently.
Offset adjustment registers
The offset adjustment variable registers are used to adjust the amplitude of the
grayscale voltage. This function is implemented by c choosing one input of 64-to-1
selector in the gamma resister stream for reference gamma voltage generation.
These registers are available for both positive and negative polarities
Gamma center adjustment registers
The gamma center adjustment registers are used to adjust the reference gamma
voltage in the middle level of grayscale without changing the dynamic range. This
function is implemented by choosing one input of 128-to-1 selector in the gamma
resister stream for reference gamma voltage generation. These registers are
available for both positive and negative polarities.
Gamma macro adjustment registers
The gamma macro adjustment registers can be used for fine adjustment of the
reference gamma voltage. This function is implemented by controlling the 32-to-1
selectors (PKP/N0~5), each of which has 5 inputs and generates one reference
voltage output (Vg(P/N) 3, 20, 32(31), 43, 60).

5.14 Content Adaptive Brightness Control (CABC) function

The HX8347-I has support Content Adaptive Brightness Control (CABC) Function and
will output one PWM signal to external LED Driver IC. The PWM signal is automatics
adjust output duty by display image for saving LED backlight power consumption.

5.14.1 Module architectures

The HX8347-I can support two module architectures for CABC operation. The BL bit
setting of R3Dh can be used to select used display module architecture. White LED
driver circuit for display backlight is located on the main PWB, not in the display
module both in architecture I and II.
Architecture I
CABC_
PWM_OUT
1. BL =`1` of R3Dh
2. LED backlight brightness for the
display is controlled by external
output CABC_PWM_OUT.
Architecture II
1. BL =`0` of R3Dh
2. LED backlight brightness data for
the display is read with DBV[7:0] bits
of R3Ch.
3. Read commands R3Ch should be
synchronized with V-sync.

5.14.2 Brightness control block

There is an external output signal from brightness block, CABC_PWM_OUT, to
control the LED driver IC in order to control display brightness.
There are resister bits, DBV[7:0] of R3Ch, for display brightness of manual brightness
setting. The CABC_PWM_OUT duty is calculated as DBV[7:0]/255 x CABC duty
(generated after one-frame display data content analysis).
For example: CABC_PWM_OUT period = 2.95 ms, and DBV[7:0](R3Ch) = 228DEC
and CABC duty is 74%. Then CABC_PWM_OUT duty = 228 / 255 x 74% 65.90%.
Correspond to the CABC_PWM_OUT period = 2.95 ms, the high-level of
CABC_PWM_OUT (high effective) = 1.94ms, and the low-level of CABC_PWM_OUT
= 1.01ms.

Figure 5-41: CABC_PWM_OUT output duty
When Architecture II module is used (BL=0) with the example below, the
CABC_PWM_OUT is always output low and the DBV[7:0](R3Ch) will be read a value
as 169DEC (169/255 66.27%).

5.14.3 Minimum brightness setting of CABC function

CABC function is automatically reduced backlight brightness based on image
contents. In the case of the combination with the CABC or manual brightness setting,
display brightness is too dark. It must affect image quality degradation. CABC
minimum brightness setting (CMB[7:0] bits of R3Fh) works to avoid too much
brightness reduction.
When CABC is active, CABC can not reduce the display brightness to less than
CABC minimum brightness setting. Image processing function works as normal, even
if the brightness can not be changed.
This function does not affect the other function, manual brightness setting. Manual
brightness can be set the display brightness to less than CABC minimum brightness.
Smooth transition and dimming function can work as normal.
When display brightness is turned off (BCTRL=0 of R3Dh), CABC minimum
brightness setting is ignored. Read CABC minimum brightness CMB[7:0] (R3Fh)
always reads the setting value.
5.14.4 Display dimming
A dimming function (how fast to change the brightness from old to new level and what
are brightness levels during the change) is used when changing from one brightness
level to another to avoid flicker in the actual display module. This dimming function
curve is the same in increment and decrement directions.

DATA SHEET V01
These commands (PAGE0 -0E~0Fh, R10~11h, R12~13h) define the Vertical

Scrolling Area of the display.
TFA[15:0] describes the Top Fixed Area (in No. of lines from Top of the Frame
Memory and Display).
VSA[15:0] describes the height of the Vertical Scrolling Area (in No. of lines of the
Frame Memory [not the display] from the Vertical Scrolling Start Address). The first
line read from Frame Memory appears immediately after the bottom most line of the
Top Fixed Area.
BFA[15:0] describes the Bottom Fixed Area (in No. of lines from Bottom of the Frame
Memory and Display).
TFA, VSA and BFA refer to the Frame Memory Line Pointer.
Please note that (TFA+VSA+BFA) must be set to 320d, otherwise Scrolling mode is
undefined. In Vertical Scroll Mode, MV bit should be set to 0 this only affects the
Frame Memory Write.

-0Eh~R13h), which describe the scrolling area and the scrolling mode.
VSP[15:0] refers to the Frame Memory line Pointer, and describes the address of the
line in the Frame Memory that will be written as the first line after the last line of the
Top Fixed Area on the display as illustrated below:
Example:
When Top Fixed Area TFA = 00d, Bottom Fixed Area BFA = 02d, Vertical Scrolling
Area VSA = 318'd and VSP = 3d (SS_Panel = 0, GS_Panel = 0)

These commands are used to set internal oscillator related setting

OSC_EN: Enable internal oscillator, OSC_EN = 1, internal oscillator start to oscillate.
OSC_EN = 0, internal oscillator stop. In RGB interface mode (PAGE0 -RCM[1:0] =
10 or 11), internal oscillator will be stop to oscillate and OSC_EN bit control is
invalid.
N_UADJ[2:0]: Internal oscillator frequency adjusts in Normal / Partial mode.
I_UADJ[2:0]: Internal oscillator frequency adjusts in Idle(8-color) / Partial Idle mode.

= 1. When D1=0, the display is off with the entire source outputs are set to the
VSSD level. Because of this, the HX8347-I can control the charging current for the
LCD with AC driving. Control the display on/off while control GON and DTE.
When D[1:0]= 01, the internal display of the HX8347-I is performed although the
actual display is off. When D[1:0]= 00, the internal display operation halts and the
display is off.
