This pin is connected to DI input of the serial EEPROM.
EEPROM Serial Clock
A 4
This pin is connected to DO output of the serial EEPROM when EEEN is pull-up.
This pin can be pull-down for 8-bit bus mode, pull-up for 16-bus mode or don’t care
for 32-bus mode when EEEN is pull-down (without EEPROM).
Synchronous Write/Read
Write/Read signal for synchronous bus accesses. Write cycles when high and Rea
