16.4.6
If the slave address matches to the address in the first frame (address reception frame) following
the start condition detection when the 8th bit data (R/W) is 1 (read), the TRS bit in ICCR is
automatically set to 1 and the mode changes to slave transmit mode.
Figure 16.17 shows the sample flowchart for the operations in slave transmit mode.

[10] Wait for stop condition
following the start condition detection and the R/W bit is 1 in
slave recieve mode, the mode changes to slave transmit mode.
