Bit 2 Output Compare Flag B (OCFB): Bit 2 is a status flag that indicates that the FRC value
has matched OCRB. This flag is set by hardware and cleared by software. It cannot be set by
software.
Bit 2: OCFB
0
1
Bit 1 Timer Overflow Flag (OVF): Bit 1 is a status flag that indicates that FRC has overflowed
from H'FFFF to H'0000. This flag is set by hardware and cleared by software. It cannot be set by
software.
Bit 1: OVF
0
1
Bit 0 Counter Clear A (CCLRA): Bit 0 selects whether or not to clear FRC by compare match
A (when FRC matches OCRA).
Bit 0: CCLRA
0
1
Description
Clearing condition:
After reading OCFB = 1, cleared by writing 0 to OCFB
Setting condition:
Set when FRC matches OCRB
Clearing condition:
After reading OVF = 1, cleared by writing 0 to OVF
Setting condition:
Set when the FRC value overflows from H'FFFF to H'0000
Description
FRC is not cleared by compare match A
FRC is cleared by compare match A
