Description

Flash memory chip enable 7-0 :

In linear 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.

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

only when port 601Eh bit 2 is set.

In linear mode, this signal is used as deep power-down

control of flash memory chips of bank0. PWD0# is active

low and also locks out erase or program operation providing

data protection during power transitions. Power down pin

PWD0# will be active if FA23=1.

In series mode, this signal is used to protect the device from

inadvertent programming or erasing. WP# is active low.

In linear mode, this signal is used as deep power-down

control of flash memory chips of bank1. PWD1# is active

low and also locks out erase or program operation providing

data protection during power transitions. Power down pin

PWD0# will be active if FA23=0. In series mode,this signal

is used to spare area control. SE# is active low.

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.
