At the end of data transfer (rise of the 8th
transmit/receive clock with serial format selected and
rise of the 9th transmit/receive clock with formatless
selected)
When a start condition is detected with serial format
selected
When the SW bit in DDCSWR is set to 1
When a start condition is detected in transmit mode
(when a start condition is detected in transmit mode
and the ICDRE flag is set to 1)
When data is transferred among the ICDR register and
buffer (when data is transferred from ICDRT to ICDRS
in transmit mode and the ICDRE flag is set to 1, or
when data is transferred from ICDRS to ICDRR in
receive mode and the ICDRF flag is set to 1)
When 0 is written in IRIC after reading IRIC = 1
When ICDR is read from or written to by the DTC (This
may not function as a clearing condition depending on
the situation. For details, see the description of the DTC
