Initial value

Read/Write

Note: * Can only be written with 0 for flag clearing.

[Clearing condition]

When 0 is written to TCFV after reading TCFV = 1

Overflow Flag

[Setting condition]

When the TCNT value overflows (changes from H'FFFF to H'0000 )

[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

Input Capture/Output Compare Flag D

[Setting conditions]

[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

Input Capture/Output Compare Flag C

[Setting conditions]

[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 B

[Setting conditions]

[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

DTA bit of DMABCR in DMAC is 1

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

Input Capture/Output Compare Flag A

[Setting conditions]

• When TCNT=TGRA while TGRA is function-

ing as output compare register

• When TCNT value is transferred to TGRA by

input capture signal while TGRA is functioning as

input capture register

• 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

• When TCNT = TGRC while TGRC is functioning as output compare

• When TCNT value is transferred to TGRC by input capture signal

while TGRC is functioning as input capture register

• 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
