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