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
command has been issued from the master, the device
initiates the internally-timed write cycle. ACK polling
can then 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 the
cycle is complete, the device will return the ACK and
the master can then proceed with the next Read or
Write command. See Figure 5-1 for a flow diagram of
this operation.

WRITE-PROTECTION
The 24XX01 can be used as a serial ROM when the
WP pin is connected to V
CC
. Programming will be
inhibited and the entire memory will be write-protected.
