Bit 4
ICFD
0
1
Description
[Clearing condition]
Read ICFD when ICFD = 1, then write 0 in ICFD
[Setting condition]
When an input capture signal is received
(Initial value)
Bit 3—Output Compare Flag A (OCFA): This status flag indicates that the FRC value matches
the OCRA value. This flag must be cleared by software. It is set by hardware, however, and
cannot be set by software.

OCFA
0
1
Description
[Clearing condition]
Read OCFA when OCFA = 1, then write 0 in OCFA
[Setting condition]
When FRC = OCRA
(Initial value)
Bit 2—Output Compare Flag B (OCFB): This status flag indicates that the FRC value matches
the OCRB value. This flag must be cleared by software. It is set by hardware, however, and cannot
be set by software.
Bit 2
OCFB
0
1
Description
[Clearing condition]
Read OCFB when OCFB = 1, then write 0 in OCFB
[Setting condition]
When FRC = OCRB
(Initial value)
Bit 1—Timer Overflow Flag (OVF): This status flag indicates that the FRC has overflowed
(changed from H'FFFF to H'0000). This flag must be cleared by software. It is set by hardware,
however, and cannot be set by software.
