Bit 3—Input Capture/Output Compare Flag D (TGFD): Status flag that indicates the

occurrence of TGRD input capture or compare match in channel 0.

In channels 1, and 2, bit 3 is reserved. It is always read as 0 and cannot be modified.

Bit 3

TGFD

Description

[Clearing conditions]

(Initial value)

• When DTC is activated by TGID interrupt while DISEL bit of MRB in DTC is 0 with

the transfer counter not being 0

• When 0 is written to TGFD after reading TGFD = 1

[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

Bit 2—Input Capture/Output Compare Flag C (TGFC): Status flag that indicates the

occurrence of TGRC input capture or compare match in channel 0.

In channels 1, and 2, bit 2 is reserved. It is always read as 0 and cannot be modified.

Bit 2

TGFC

Description

[Clearing conditions]

(Initial value)

• When DTC is activated by TGIC interrupt while DISEL bit of MRB in DTC is 0 with

the transfer counter not being 0

• When 0 is written to TGFC after reading TGFC = 1

[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
