PAGE WRITE OPERATION
The S524LB0D91/B0DB1 can also perform 32-byte page write operation. A page write operation is initiated in the
same way as a byte write operation. However, instead of finishing the write operation after the first data byte is
transferred, the master can transmit up to 31 additional bytes. The S524LB0D91/B0DB1 responds with an ACK
each time it receives a complete byte of data (see Figure 7-11).

Figure 7-11. Page Write Operation
The S524LB0D91/B0DB1 automatically increments the word address pointer each time it receives a complete
data byte. When one byte is received, the internal word address pointer increments to the next address so that
the next data byte can be received.
If the master transmits more than 32 bytes before it generates a stop condition to end the page write operation,
the S524LB0D91/B0DB1 word address pointer value “rolls over” and the previously received data is overwritten.
If the master transmits less than 32 bytes and generates a stop condition, the S524LB0D91/B0DB1 writes the
received data to the corresponding EEPROM address.
During a page write operation, all inputs are disabled and there would be no response to additional requests from
the master until the internal write cycle is completed.
