D/CX

(SCL)

-Display data/command Selection Pin in MCU Interface.

-D/CX=’1’: Display Data or Parameter.

-D/CX=’0’: Command Data.

-In Serial Interface, this is used as SCL.

-If not used, please fix this pin at VDDI or DGND level.

MCU

RDX

-Read Enable in 8080 MCU Parallel Interface.

-If not used, please fix this pin at VDDI or DGND level.

MCU

WRX

(D/CX)

-Write Enable in MCU Parallel Interface.

-In 4-line SPI, this pin is used as D/CX (data/ command selection).

-If not used, please fix this pin at VDDI or DGND level.

MCU

D[17:0]

I/O

-D[17:0] are used as MCU parallel interface data bus.

-D0 is the serial input/output signal in serial interface mode.

-In serial interface, D[17:1] are not used and should be fixed at VDDI or

DGND level.

MCU

-Tearing effect output pin to synchronies MCU to frame rate, activated

by S/W command.

-If not used, please open this pin.

MCU

OSC

-Monitoring pin of internal oscillator clock and is turned ON/OFF by

S/W command.

-When this pin is inactive (function OFF), this pin is DGND level.

-If not used, please open this pin.

Note1. When in parallel mode, no use data pin must be connected to “1” or “0”.

Note2. When CSX=”1”, there is no influence to the parallel and serial interface.
