This section describes the requirements and use of the device bus operations, which are ini-
tiated 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.
they require, and the resulting output. The following subsections describe each of these op-
erations in further detail.
The BYTE# pin controls whether the device data I/O pins operate in the byte or word config-
uration. If the BYTE# pin is set at logic ‘1’, the device is in word configuration, 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 pins DQ8–DQ14 are
tri-stated, and the DQ15 pin is used as an input for the LSB (A-1) address function.
The VersatileIO
