of the IRIC flag to 0 should be performed consecutively, with no interrupt processing
occurring between them. During wait operation, clear the IRIC flag to 0 when the value of
counter BC2 to BC0 is 2 or greater. If the IRIC flag is cleared to 0 when the value of counter
BC2 to BC0 is 1 or 0, it will not be possible to determine when the transfer has completed. If
condition [3]-1 is true, the master device drives SDA to low level and returns an
acknowledge signal when the receive clock outputs the 9th clock cycle.

clear the IRIC flag to 0 when the value of counter BC2 to BC0 is 2 or greater.
SCL is automatically held low, in synchronization with the internal clock, until the IRIC
flag is cleared.
The IRTR flag is set to 1, indicating that reception of 1 frame of data has ended. The
master device continues to output the receive clock for the receive data.
