15.4.7
The interrupt request flag (IRIC) is set at different times depending on the WAIT bit in ICMR, the
FS bit in SAR, and the FSX bit in SARX. If the ICDRE or ICDRF flag is set to 1, SCL is
automatically held low after one frame has been transferred; this timing is synchronized with the
internal clock. Figures 15.25 to 15.27 show the IRIC set timing and SCL control.

IRIC Setting Timing and SCL Control
(a) Data transfer ends with ICDRE=0 at transmission, or ICDRF=0 at reception.
(b) Data transfer ends with ICDRE=1 at transmission, or ICDRF=1 at reception.
