Input Capture/Output Compare Flag B
Status flag that indicates the occurrence of TGRB
input capture or compare match.
[Setting conditions]
• When TCNT = TGRB while TGRB is
functioning as output compare register
• When TCNT value is transferred to TGRB by
input capture signal while TGRB is functioning
as input capture register
[Clearing conditions]
• When DTC is activated by TGIB interrupt while
DISEL bit of MRB in DTC is 0
• When 0 is written to TGFB after reading TGFB
= 1

Input Capture/Output Compare Flag A
Status flag that indicates the occurrence of TGRA
input capture or compare match.
[Setting conditions]
• When TCNT = TGRA while TGRA is
functioning as output compare register
• When TCNT value is transferred to TGRA by
input capture signal while TGRA is functioning
as input capture register
[Clearing conditions]
• When DTC is activated by TGIA interrupt while
DISEL bit of MRB in DTC is 0
• When DMAC is activated by TGIA interrupt
while DTE bit of DMABCR in DTC is 1*
2
• When 0 is written to TGFA after reading TGFA
= 1
Notes: 1. Only 0 can be written, for flag clearing.
2. Only available in unit 0.
