Section 14 I
14.4.6
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 14.17 shows the sample flowchart for the operations in slave transmit mode.

[3], [4] Wait for 1 byte to be transmitted.
[6] Read IRIC in ICCR
[1], [2] If the slave address matches to the address in the first frame
[7] Clear acknowledge bit data
[8] Set slave receive mode.
[4] Determine end of transfer.
[9] Dummy read (to release the SCL line).
[10] Wait for stop condition
[3], [5] Set transmit data for the second and subsequent bytes.
following the start condition detection and the R/W bit is 1
in slave recieve mode, the mode changes to slave transmit mode.
