In slave receive mode, the master device outputs the transmit clock and transmit data, and the
slave device returns an acknowledge signal.
The slave device compares its own address with the slave address in the first frame following the
establishment of the start condition issued by the master device. If the addresses match, the slave
device operates as the slave device designated by the master device.
Figure 15-14 is a flowchart showing an example of slave receive mode operation.
