R/(W)*

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 with the transfer

counter not being 0

• When 0 is written to TGFB after reading TGFB =

0TGFA

R/(W)*

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 with the transfer

counter not being 0

• When DMAC is activated by TGIA interrupt

while DTE bit of DMABCR in DMAC is 1*

• When 0 is written to TGFA after reading TGFA =

Notes: 1. Only 0 can be written, for flag clearing.

2. Supported only by the H8S/2239 Group.

3. Not available in the H8S/2227 Group.
