Bit 2—Overflow Flag (OVF): This status flag indicates TCNT overflow or underflow.
Note:
Bit 1—Input Capture/Compare Match Flag B (IMFB): This status flag indicates GRB
compare match or input capture events.
Bit 0—Input Capture/Compare Match Flag A (IMFA): This status flag indicates GRA
compare match or input capture events.

* TCNT underflow occurs when TCNT operates as an up/down-counter. Underflow
occurs only under the following conditions:
(1) Channel 2 operates in phase counting mode (MDF = 1 in TMDR)
(2) Channels 3 and 4 operate in complementary PWM mode (CMD1 = 1 and CMD0 = 0
in TFCR)
Description
[Clearing condition]
Read OVF when OVF = 1, then write 0 in OVF
[Setting condition]
TCNT overflowed from H'FFFF to H'0000, or underflowed from H'0000 to
H'FFFF *
Description
[Clearing condition]
Read IMFB when IMFB = 1, then write 0 in IMFB
[Setting conditions]
TCNT = GRB when GRB functions as an output compare register.
TCNT value is transferred to GRB by an input capture signal, when GRB
functions as an input capture register.
Description
[Clearing conditions]
Read IMFA when IMFA = 1, then write 0 in IMFA.
DMAC activated by IMIA interrupt (channels 0 to 3 only).
[Setting conditions]
TCNT = GRA when GRA functions as an output compare register.
TCNT value is transferred to GRA by an input capture signal, when GRA
functions as an input capture register.
