7. FUNCTIONAL DESCRIPTION
7.1 Device operation
This section describes the requirements and use
of the device bus operations, which are initiated
through the internal command register. The
register is composed of latches that store the
command, 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
