Bit 7: Compare match flag B
0
[Clearing]
(1) Reading CMFB then writing 0 to CMFB when CMFB=1
(2) When DTC is started by CMIB interrupt and DTC MRB DISEL bit is 0
1
[Setting]
When TCNT=TCORB
Bit 6: Compare match flag A
0
[Clearing]
(1) Reading CMFA then writing 0 to CMFA when CMFA=1
(2) When DTC is started by CMIA interrupt and DTC MRB DISEL bit is 0
