P/S

The input pin to select the parallel or serial interface.

“L” selects the parallel interface.

“H” selects the serial interface.

The pin to enable this IC in the serial I/F mode.

“L” enables this IC.

“H” disables this IC.

This pin should be open in the parallel I/F mode.

SHT

The pin to input shift clock in the serial I/F mode.

Data inputting to the SI pin is carried out synchronizing with the rising edge of this

clock signal.

Data outputting from the SO pin is carried out synchronizing with the falling edge of this

clock signal.

This pin should be open in the parallel I/F mode.

The pin to input DATA in the serial I/F mode.

Data inputting to this pin is carried out synchronizing with the rising edge of the SHT

signal.

This pin should be open in the parallel I/F mode.

The pin to output DATA in the serial I/F mode.

Data inputting to this pin is carried out synchronizing with the falling edge of the SHT

signal.

This pin should be open in the parallel I/F mode.

Symbol
