功能說明

I/O

GND

Ground

2-6

No connection

VCI

High voltage power supply for analog circuit blocks
(2.5 ~ 3.3 V)

IOVCC

Low voltage power supply for interface logic circuits
(2.5 ~ 3.3 V)

Tearing effect output pin to synchronize MPU to frame writing, activated by S/W command. When this pin is not activated, this pin is low.
If not used, open this pin.

Chip select signal.

D/CX(SCL)

(D/CX): This pin is used to select “Data or Command” in the parallel interface.
When DCX = 1, data is selected.
When DCX = 0, command is selected.
(SCL): This pin is used as the serial interface clock in 3-wire
9-bit/4-wire 8-bit serial data interface.
If not used, this pin should be connected to IOVCC or GND.

WR(SPI_D/C)

(WRX) - 8080-Ⅰ/8080-Ⅱ system: Serves as a write signal and writes data at the rising edge.
(D/CX) - 4-line system: Serves as the selector of command or parameter.
Fix to IOVCC level when not in use.

8080-Ⅰ/8080-Ⅱ system (RDX): Serves as a read signal and MCU read data at the rising edge.
Fix to IOVCC level when not in use.

14-29

DB0~DB15

18-bit parallel bi-directional data bus for MCU system.
Fix to GND level when not in use.

I/O

RESET

(RESX)This signal will reset the device and must be applied to properly initialize the chip.
Signal is active low.

IM0
