POLLING FOR AN ACK SIGNAL
When the master issues a stop condition to initiate a write cycle, the TMC 24A01/24A02/24A04/24A08/24A16
starts an internal write cycle. The master can then immediately begin polling for an ACK from the slave device.
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 TMC 24A01/24A02/24A04/24A08/24A16 remains busy with the write operation, no ACK is
returned. When the TMC 24A01/24A02/24A04/24A08/24A16 completes the write operation, it returns an ACK
and the master can then proceed with the next read or write operation (see Figure 3-11).
