(November, 2007, Version 1.3)
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

machine outputs dictate the function of the device. The
appropriate device bus operations table lists the inputs
and control levels required, and the resulting output. The
following subsections describe each of these operations
in further detail.
*Comments
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to this device.
These are stress ratings only. Functional operation of this
device at these or any other conditions above those
indicated in the operational sections of these specification is
not implied or intended. Exposure to the absolute maximum
rating conditions for extended periods may affect device
reliability.
