15.3.6
In slave transmit operation, the slave device compares its own address with the slave address
transmitted by the master device in the first frame (address receive frame) following detection of
the start condition. If the addresses match and the 8th bit (R/W) is set to 1 (read), the TRS bit in
ICCR is automatically set to 1 and slave transmit mode is activated.
Figure 15-17 is a flowchart showing an example of slave transmit mode operation.
