ACKNOWLEDGE POLLING
Since the device will not acknowledge an EEPROM
command during an EEPROM 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 3-4 for the
flow diagram.
