Underflow flag
0
[Clearing condition]
Writing 0 to TCFU after reading TCFU=1.
1
[Setting condition]
When the TCNT value underflows (H’0000 → H’FFFF).
Count direction flag
0
TCNT counts down.
1
TCNT counts up.
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 B
0
[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.
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*² is started by a TGIA interrupt and the DTC*² 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.
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.
Notes: *1 Only 0 can be written to these bits (to clear these flags).
*2 This function is not available in the H8S/2695.
