Note:
When, with the I
must be checked in order to identify the source that set IRIC to 1. Although each source has a
corresponding flag, caution is needed at the end of a transfer.
When the ICDRE or ICDRF flag is set, the IRTR flag may or may not be set. The IRTR flag is not
set at the end of a data transfer up to detection of a retransmission start condition or stop condition
after a slave address (SVA) or general call address match in I
Tables 13.4 and 13.5 show the relationship between the flags and the transfer states.

[Clearing conditions]

At the end of data transfer (rise of the 8th
transmit/receive)
When a start condition is detected
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 ICDR 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
