ACKNOWLEDGE POLLING
FIGURE 7-1:
ACKNOWLEDGE
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
command has been issued from the master, the device
initiates the internally timed write cycle. ACK polling
can be initiated immediately. This involves the master
sending 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 no ACK is returned, then the Start bit and control byte
must be resent. 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 7-1
for flow diagram.

Note:
Care must be taken when polling the
24XX1025. The control byte that was
used to initiate the write needs to match
the control byte used for polling.
