ACKNOWLEDGE POLLING
Acknowledge polling can be done for both the DDC
Monitor Port (when in Bi-directional Mode) and the
Microcontroller Access Port.
Since the port 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 but
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 (R/W=0). If the device is still busy with
the write cycle, then no ACK will be returned. If the
cycle is complete, then the device will return the ACK
and the master can then proceed with the next read or
write command. See Figure 5-1 for the flow diagram.
