Bit 7: ICF
0
1
Bits 6 to 4—Reserved: These bits always read 0. The write value should always be 0.
Bit 3—Output Compare Flag A (OCFA): Status flag that indicates when the values of the FRC
and OCRA match. This flag is cleared by software and set by hardware. It cannot be set by
software.
Bit 3: OCFA
0
1
Bit 2—Output Compare Flag B (OCFB): Status flag that indicates when the values of FRC and
OCRB match. This flag is cleared by software and set by hardware. It cannot be set by software.
Bit 2: OCFB
0
1
Bit 1—Timer Overflow Flag (OVF): Status flag that indicates when FRC overflows (from H'FFFF
to H'0000). This flag is cleared by software and set by hardware. It cannot be set by software.
Bit 1: OVF
0
1
Bit 0—Counter Clear A (CCLRA): Selects whether or not to clear FRC on compare match A
(signal indicating match of FRC and OCRA).
Bit 0: CCLRA
0
1
Description
Clear conditions: When ICF is read while set to 1, and then 0 is written
to it
Set conditions: When the FRC value is sent to FICR by the input
capture signal
Description
Clear conditions: When OCFA is read while set to 1, and then 0 is
written to it
Set conditions: When the FRC value becomes equal to OCRA
Description
Clear conditions: When OCFB is read while set to 1, and then 0 is
written to it
Set conditions: When the FRC value becomes equal to OCRB
Description
Clear conditions: When OVF is read while set to 1, and then 0 is
written to it
Set conditions: When the FRC value changes from H'FFFF to H'0000
