ACKNOWLEDGE POLLING
Since the device will not acknowledge during a write
cycle, this can be used to determine when the cycle is
complete (this feature can be used to maximize bus
throughput). Once the stop condition for a write com-
mand has been issued from the master, the device ini-
tiates the internally timed write cycle. ACK polling can
be initiated immediately. This involves the master send-
ing a start condition followed by the control byte for a
write command and then sending the Device ID byte for
that particular device. If the device is still busy with the
write cycle, then no ACK will be returned after the
Device ID byte. If no ACK is returned, then the start bit,
control byte and ID byte must be re-sent. If the cycle is
complete, then the device will return the ACK and the
master can then proceed with the next command. See
Figure 7-1 for flow diagram.
