Input Capture/Output Compare Flag D
Status flag that indicates the occurrence of TGRD
input capture or compare match in channels 0 and
3.
In channels 1, 2, 4, and 5, bit 3 is reserved. It is
always read as 0 and cannot be modified.
[Setting conditions]
• When TCNT = TGRD while TGRD is
functioning as output compare register
• When TCNT value is transferred to TGRD by
input capture signal while TGRD is functioning
as input capture register
[Clearing conditions]
• When DTC is activated by TGID interrupt while
DISEL bit of MRB in DTC is 0
• When 0 is written to TGFD after reading TGFD
= 1
2 TGFC 0 R/(W)

1
Input Capture/Output Compare Flag C
Status flag that indicates the occurrence of TGRC
input capture or compare match in channels 0 and
3.
In channels 1, 2, 4, and 5, bit 2 is reserved. It is
always read as 0 and cannot be modified.
[Setting conditions]
• When TCNT = TGRC while TGRC is
functioning as output compare register
• When TCNT value is transferred to TGRC by
input capture signal while TGRC is functioning
as input capture register
[Clearing conditions]
• When DTC is activated by TGIC interrupt while
DISEL bit of MRB in DTC is 0
• When 0 is written to TGFC after reading TGFC
= 1
