6

WR

I

8080 system (WRX): Serves as a write signal and writes data at the rising edge.

4-line system (D/CX): Serves as command or parameter select.

7

/CS

I

Chip select input pin( "Low" enable). This pin can be permanently fixed "Low" in MPU interface mode only

8

/ RS

I

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.

This pin is used serial interface clock in 3-wire 9-bit / 4-wire 8-bit serial data interface.
