Description
This status flag indicates that the FRC value matches
the OCRA value.
[Setting condition]
When FRC = OCRA
[Clearing condition]
Read OCFA when OCFA = 1, then write 0 to OCFA
This status flag indicates that the FRC value matches
the OCRB value.
[Setting condition]
When FRC = OCRB
[Clearing condition]
Read OCFB when OCFB = 1, then write 0 to OCFB
This status flag indicates that the FRC has overflowed.
[Setting condition]
When FRC overflows (changes from H'FFFF to H'0000)
[Clearing condition]
Read OVF when OVF = 1, then write 0 to OVF
Counter Clear A
Selects whether FRC is to be cleared at compare-
match A (when the FRC and OCRA values match).
0: FRC clearing is disabled
1: FRC is cleared at compare-match A
