13. Notes on ICDR Reads in Transmit Mode and ICDR Writes in Receive Mode
14. Notes on ACKE Bit and TRS Bit in Slave Mode
15. Notes on Arbitration Lost in Master Mode
When attempting to read ICDR in the transmit mode (TRS = 1) or write to ICDR in the receive
mode (TRS = 0) under certain conditions, the SCL pin may not be held low after the
completion of the transmit or receive operation and a clock may not be output to the SCL bus
line before the ICDR register access operation can take place properly.
When accessing ICDR, always change the setting to the transmit mode before performing a
read operation, and always change the setting to the receive mode before performing a write
operation.
When using the I
1 is received as an acknowledge bit (ACKB = 1) in the transmit mode (TRS = 1), an interrupt
may be generated at the rising edge of the 9th clock cycle if the address does not match.
When performing slave mode operations using the IIC bus interface module, make sure to do
the following.
(1) When a 1 is received as an acknowledge bit for the final transmit data after completing a

The I
arbitration is lost in master mode and a transition to slave receive mode is automatically
carried out.
When arbitration is lost not in the first frame but in the second frame or subsequent frame,
transmit/receive data that is not an address is compared with the value set in the SAR or SARX
register as an address. If the receive data matches with the address in the SAR or SARX
register, the I

receive mode is accomplished properly, end the transmission as described in figure 16.17.
