POLLING FOR AN ACK SIGNAL
When the master issues a stop condition to initiate a write cycle, the S524LB0D91/B0DB1 starts an internal write
cycle. The master can then immediately begin polling for an ACK from the slave device to determine whether the
write cycle is completed.
To poll for an ACK signal in a write operation, the master issues a start condition followed by the slave address.
As long as the S524LB0D91/B0DB1 remains busy with the write operation, no ACK is returned. When the
S524LB0D91/B0DB1 completes the write operation, it returns an ACK and the master can then proceed with the
next read or write operation (see Figure 7-12).
