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 TDRE or RDRF internal flag is set, the readable IRTR flag may or may not be set. Even
when data transfer is complete, the DTC activation request flag, IRTR, is not set until a
retransmission start condition or stop condition is detected after a slave address (SVA) or general
call address matched in the I
Even when the IRIC flag and IRTR flag are set, the TDRE or RDRF internal flag may not be set.
For a continuous transfer using the DTC, the IRIC or IRTR flag is not cleared at the completion of
the specified number of times of transfers. On the other hand, the TDRE and RDRF flags are
cleared because the specified number of times of read/write operations have been complete.
Table 16.4 shows the relationship between the flags and the transfer states.

Description
Start Condition/Stop Condition Prohibit bit
The SCP bit controls the issue of start/stop conditions in
master mode.
To issue a start condition, write 1 in BBSY and 0 in SCP. A
retransmit start condition is issued in the same way. To issue
a stop condition, write 0 in BBSY and 0 in SCP. This bit is
always read as 1. If 1 is written, the data is not stored.
