Description
Overflow Flag
Status flag that indicates that TCNT overflow has
occurred. Only 0 can be written, for flag clearing.

[Clearing condition]

Input Capture/Output Compare Flag D
Status flag that indicates the occurrence of TGRD input
capture or compare match in channels 0, 3, and 4. Only
0 can be written, for flag clearing. In channels 1 and 2,
bit 3 is reserved. It is always read as 0 and the write
value should always be 0.
[Setting conditions]

•
[Clearing conditions]
•
•
When the TCNT value overflows (changes from
H'FFFF to H'0000)
In channel 4, when the TCNT_4 value underflows
(changes from H'0001 to H'0000) in complementary
PWM mode, this flag is also set.
When 0 is written to TCFV after reading TCFV = 1*
In channel 4, when DTC is activated by TCIV
interrupt and the DISEL bit of MRB in DTC is 0, this
flag is also cleared.
When TCNT = TGRD and TGRD is functioning as
output compare register
When TCNT value is transferred to TGRD by input
capture signal and TGRD is functioning as input
capture register
When DTC is activated by TGID interrupt and the
DISEL bit of MRB in DTC is 0
When 0 is written to TGFD after reading TGFD = 1*
