Serial Clock/Chip Select.
When SER is LOW, SCL is the clock
line of the serial interface. When SER is HIGH, the pin is the chip
select control for the parallel interface. When CS is HIGH, the

Serial/Parallel Port Select.
When LOW, the 2-line serial
interface is activated. Pins 5, 6, and 7 function as SA
SCL respectively. When HIGH, the parallel interface port is active
and pins 5, 6, and 7 function as ADR, R/W, and CS respectively.
