DEVICE BUS OPERATIONS
This section describes the requirements and use of
the device bus operations, which are initiated through
the internal command register. The command register
itself does not occupy any addressable memory loca-
tion. The register is a latch used to store the com-
mands, along with the address and data information
needed to execute the command. The contents of the

Notes:
1. Addresses are A22:A0 in word mode; A22:A-1 in byte mode. Sector addresses are A22:A15 in both modes.
2. The sector group protect and sector group unprotect functions may also be implemented via programming equipment. See the

Word/Byte Configuration
The BYTE# pin controls whether the device data I/O
pins operate in the byte or word configuration. If the
BYTE# pin is set at logic ‘1’, the device is in word con-
figuration, DQ0–DQ15 are active and controlled by
CE# and OE#.
If the BYTE# pin is set at logic ‘0’, the device is in byte
configuration, and only data I/O pins DQ0–DQ7 are
active and controlled by CE# and OE#. The data I/O
