Serial data input (positive logic).
Input from LSB.
Shift clock input.
Serial data is shifted on the rising edge of CP.
Chip select input.
Serial data transfer is disabled when CS pin is "H" level.
Reset input.
"Low" initializes all the functions.
Initial status is as follows.
• Address of each RAM
