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 Read
cycles when low.
Address Enable
Address qualifier for the address decoding, active Low.
Write Strobe Not
Asynchronous write strobe, active Low.
Digital IO ground
Address Strobe Not
For systems that require address latching, the rising edge of ADSN indicates the
latching moment of A15-A1 and AEN.
Full-chip power-down. Active Low (Low = Power down; High = Normal operation).
