Description
These pins constitute 4-bit general-purpose input port
Output serial data at falling edge of shift clock, starting
from lower bit. This is N-ch open-drain output pin.
Inputs serial data at rising edge of shift clock, starting
from lower bit.
Be sure to leave this pin open (this pin is at VDD level)
