Device Bus Operations
Word/Byte Configuration
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 location.
The register is a latch used to store the commands, along with the address and data information needed to
execute the command. The contents of the register serve as inputs to the internal state machine. The state
machine outputs dictate the function of the device.
control levels they require, and the resulting output. The following subsections describe each of these
operations in further detail.

Notes:
1. Addresses are A21:A0 in word mode (BYTE# = V
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See
3. If WP#/ACC = V
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 configuration, DQ15–DQ0 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 DQ7–DQ0 are
active and controlled by CE# and OE#. The data I/O pins DQ14–DQ8 are tri-stated, and the DQ15 pin is used
as an input for the LSB (A-1) address function.
