[Clearing condition]
When 0 is written to TCFV after reading
TCFV = 1*

[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.

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.

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

[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
