Acknowledge Polling:
Acknowledge polling feature is used to show if the EEPROM is in a internally-timed write cycle or not.
This feature is initiated by the stop condition after inputting write data. This requires the 8-bit device
address word following the start condition during a internally-timed write cycle. Acknowledge polling will
operate when the R/W code = “0”. Acknowledgment “1” (no acknowledgment) shows the EEPROM is in
a internally-timed write cycle and acknowledgment “0” shows that the internally-timed write cycle has
completed. See Write Cycle Polling using ACK.
