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 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.
Bit 0—Counter Clear A (CCLRA): This bit selects whether the FRC is to be cleared at compare-
match A (when the FRC and OCRA values match).
