RCM0
I

RCM1
I
When RCM1, RCM0=‘1X’(RGB I/F), serial input/output signal in serial I/F mode.
The data is input on the rising edge of the SCL signal. The data is output on the
9
SDA
I
falling edge of the SCL signal.
When RCM1, RCM0=‘0X’(MCU I/F), this pin is not used, and fix at VDDI or
GND level.
If not used, please fix this pin at VDDI or GND level.
10
VCC
--- Power supply 2.8V
11 GND / VSS --- Power ground 0V
Read enable in 8080-parallel interface and Read/ Write operation enable pin in
12
RD
I
6800-parallel interface.
In 8080-parallel interface, if not used, please connect this pin to VDDI.
In 6800-parallel interface, if not used, please connect this pin to VDDI or GND.
Display data / Command selection pin in parallel and SCL in 3-pin SPI interface.
13
RS
I
RS=‘1’: Display data.
RS=‘0’: Command data.
If not used, please connect this pin to GND.
When– RCM=‘0’ (MCU I/F), D[17:0] are used to MCU parallel interface data bus,
14~31 DB17~DB0 I/O and D0 is also the serial input/ output signal in SPI interface mode.
In serial interface, D[17:1] are not used and should be connected to ground.
Tearing effect output pin to synchronies MCU to frame writing, activated by S/W
32
TE
O command. When this pin is not activated, this pin is low.
If not used, please open this pin.
Chip reset pin (“Low Active”).
33
RES
I This signal low will reset the device and must be applied to properly initialize the
chip.
34
CS
I
Chip select input pin (“Low” enable).
This pin can be permanently fixed “Low” in MCU interface mode only.
Write enable in parallel interface.
WR: for 8080 MCU
35
WR
I R/WX: for 6800 MCU
RS: for 4-wire SPI
If not used, please connect this pin to VDDI or GND.
