Description

Flash memory chip enable 7-0 :

In random mode, These signals are decoded from port 601Dh bit 7-5

when flash memory read or port 601Fh bit 7-5 when flash memory

write.

Decoding combination :

In sequential mode, These are decoded from port 601Dh bit 7-5 only

when port 601Eh bit 2 is set.

Deep power down output 0 for bank0: This signal will put the flash

memory chips of bank0 in deep power-down mode. PWD0# is active

low;PWD0# high enables normal operation. PWD0# also locks out erase

or program operation when active low providing data protection during

power transitions. Power down pin PWD0# will be active if FA23=1.

Deep power down output 1 for bank1: This signal will put the flash

memory chips of bank1 in deep power-down mode. PWD1# is active

low;PWD1# high enables normal operation. PWD1# also locks out erase

or program operation when active low providing data protection during

power transitions. Power down pin PWD1# will be active if FA23=0.

Flash memory Ready/busy input:

This signal indicate the state of erase or program operation in flash

memory chips.This pin includes an internal pull-up resistor.
