Input capture/output compare flag A
Input capture/output compare flag B
[Clearing conditions]
(1) When the DTC*
2
is started by a TGIB interrupt and the DTC*
2
MRB DISEL
bit is 0;
(2) Writing 0 to TGFB after reading TGFB=1.
[Setting conditions]
(1) When TGRB is functioning as the output compare register and TCNT=
TGRB;
(2) When TGRB is functioning as the input capture register and the value
of TCNT is sent to TGRB by the input capture signal.

MRB DISEL
bit is 0;
(2) When the DMAC*
2
is started by a TGIA interrupt and the DMAC*
2
DMABCR
DTA bit is 1;
(3) Writing 0 to TGFA after reading TGFA=1.
[Setting conditions]
(1) When TGRA is functioning as the output compare register and TCNT=
TGRA;
(2) When TGRA is functioning as the input capture register and the value
of TCNT is sent to TGRA by the input capture signal.

Overflow flag
[Clearing condition]
Writing 0 to TCFV after reading TCFV=1.
[Setting condition]
When the TCNT value overflows (H’FFFF → H’0000).
