DESCRIPTION
Output Enable Signal for Static Memory
Read/Write Signal
Ready Signal Input
When this pin is Low, current memory transfer extended.
Clock Output Signal
Active only during external cycles.
Output is same phase and speed as the bus clock
Chip Select Signal for Bank #0
NCS pins are required to be Pull-up for proper operation.
All NCS pins are Active Low See Fig.1 memory Map(Section 2)
