11. Points for caution of clearing the IRIC flag when the wait function is used
Rev.4.00 Mar. 27, 2008 Page 536 of 882
REJ09B0108-0400
While the wait function is used in I
exceeds the specified value or if a slave device in which a wait can be inserted by driving SCL
low is used, read SCL in the following way to confirm that SCL has become low, and then
clear the IRIC flag.
If the IRIC flag is cleared to 0 with WAIT = 1 while SCL is extending the high level period,
the SDA level may change before SCL becomes low, generate a start or stop condition
erroneously.

C Bus Interface (IIC) Option
If the IRIC flag-clear is delayed due to the interrupt or other processes and the value of BC
counter is turned to 1 or 0, please confirm the SCL pins are in L’ state after the counter
value of BC2 through BC0 is turned to 0, and clear the IRIC flag. (See figure 14.32.)
