Application No. 09/030,829
Rather, as shown at 3-6 above, the timing of the output of the
response status is actually taught as being discrete for each
read data. We find that if the response status (ACK) signal were
indeed to be continuous for any data read (data word), then the
device of Appellants' specification would be inoperative. Given
that the MCU inputs (or outputs) a data word for each ACK, if a
second ACK were sent in the middle of a read data (data word) by
the MCU, then the MCU would attempt a second input operation on
top of the first.
We note that had the phrase "each read data" in claim 1,
instead been "each access request signal," then the result would
be the opposite. We find that all of Appellants' specification
is directed to the timing of the output of the response status
(ACK signal) being discrete or continuous for each access request
signal. Thus, the specification would be enabled for a claim
where the MCU retrieves a data word for each ACK signal the MCU
receives, and for a single access request signal sent from the
MCU, in a first mode the HDC sends one (discrete) ACK signal and
in a second mode the HDC sends plural (continuous) ACK signals.
