Overflow flag
0
[Clearing condition]
Writing 0 to TCFV after reading TCFV=1.
1
[Setting condition]
When the TCNT value overflows (H’FFFF → H’0000).
Input capture/output compare flag D
0
[Clearing conditions]
(1) When the DTC is started by a TGID interrupt and the DTC MRB
DISEL bit is 0;
(2) Writing 0 to TGFD after reading TGFD=1.
1
[Setting conditions]
(1) When TGRD is functioning as the output compare register and
TCNT=TGRD;
(2) When TGRD is functioning as the input capture register and the value
of TCNT is sent to TGRD by the input capture signal.
Input capture/output compare flag C
0
[Clearing conditions]
(1) When the DTC is started by a TGIC interrupt and the DTC MRB
DISEL bit is 0;
(2) Writing 0 to TGFC after reading TGFC=1.
1
[Setting conditions]
(1) When TGRC is functioning as the output compare register and
TCNT=TGRC;
(2) When TGRC is functioning as the input capture register and the value
of TCNT is sent to TGRC by the input capture signal.
Input capture/output compare flag B
0
[Clearing conditions]
(1) When the DTC is started by a TGIB interrupt and the DTC MRB
DISEL bit is 0;
(2) Writing 0 to TGFB after reading TGFB=1.
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.
Input capture/output compare flag A
0
[Clearing conditions]
(1) When the DTC is started by a TGIA interrupt and the DTC MRB
DISEL bit is 0;
(2) When the DMAC is started by a TGIA interrupt and the DMAC
DMABCR DTA bit is 1;
(3) Writing 0 to TGFA after reading TGFA=1.
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.
Note: * Only 0 can be written to these bits (to clear these flags).
