9-bit/4-wire 8-bit serial data interface.
If not used, this pin should be connected to VDDI or VSS.
I
12 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 VDDI level when not in use.
