Bit Name Value R/W Description

TCFV
0
R/(W)*¹ Overflow Flag
Status flag that indicates that TCNT overflow has
occurred. Only 0 can be written, for flag clearing.
[Setting condition]
• 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.
[Clearing condition]
3
TGFD
0
• When 0 is written to TCFV after reading TCFV =
1*²
R/(W)*¹ 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]
• 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
[Clearing condition]
• When 0 is written to TGFD after reading TGFD =
1*²
