Transmitter and Receiver Timing
Note: CEN must not be active during an IACKN cycle. If CEN is
active IACKN will be ignored and a normal read or write will be
executed according to W_RN.
In the synchronous mode extended IACKN signal cycle will start
another IACKN. (This may not be desired, but is allowed.)
