RS/SPI SCL/SCK |
This pin is used to select “Data or Command” in the parallel interface or serial data interface. |
Parallel: | ||
When RS= '1',data is selected. | ||
When RS= '0',command is selected. | ||
Serial: | ||
This pin is used 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. | ||
