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 and 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, no ACK will be returned. If no
ACK is returned, the Start bit and control byte must be
re-sent. If the cycle is complete, the device will return
the ACK and the master can then proceed with the next
Read or Write command. See
diagram of this operation.
