Description
These pins constitute a 4-bit general-purpose input port.
Output serial data at the falling edge of the shift clock, starting from low
order bit. This is N-ch open-drain output pin.
Input serial data at rising edge of shift clock, starting from the low order bit.
Connect this pin to system GND.
Reads serial data at the rising edge, and outputs data at the falling edge.
Initializes serial interface at the rising or falling edge of the uPD16312. It
then waits for reception of a command. Data input after STB has fallen is
processed as a command. While command data is processed, current
processing is stopped, and the serial interface is initialized. While STB is
high, CLK is ignored.
Data input to these pins is latched at the end of the display cycle.
