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 composed of latches that 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.
inputs and control levels they require, and the resulting output. The following subsections describe each of
these operations in further detail.

Notes
1. Addresses are A19:A0 in word mode (BYTE# = V
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See
The BYTE# pin controls whether the device data I/O pins DQ15–DQ0 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 DQ0–DQ7 are
active and controlled by CE# and OE#. The data I/O pins DQ8–DQ14 are tri-stated, and the DQ15 pin is used
as an input for the LSB (A-1) address function.
