Legend
X = Don’t care
RA = Read Address of memory location to be read.
RD = Read Data read from location RA during read operation.
PA = Program Address. Addresses latch on falling edge of WE# or CE# pulse,
whichever happens later.
PD = Program Data for location PA. Data latches on rising edge of WE# or CE#
pulse, whichever happens first.
