Legend:
X = Don’t care
RA = Address of the memory location to be read.
RW = Data read from location RA during read operation.
PA = Address of the memory location to be programmed.
Addresses are latched on the falling edge of the WE# pulse.
Notes:
1. Write protect must not be enabled for proper operation of

3. All values are in hexadecimal.
4. The last bus cycle in an autoselect command sequence is
5. Word = high byte + low byte.
