TCORB match.
Bit 7
CMFB
0
1
Description
[Clearing conditions]
(Initial value)
• Cleared by reading CMFB when CMFB = 1, then writing 0 to CMFB
• When DTC is activated by CMIB interrupt while DISEL bit of MRB in DTC is 0
[Setting condition]
Set when TCNT matches TCORB
Bit 6—Compare Match Flag A (CMFA): Status flag indicating whether the values of TCNT and
TCORA match.
Bit 6
CMFA
0
1
Description
[Clearing conditions]
(Initial value)
• Cleared by reading CMFA when CMFA = 1, then writing 0 to CMFA
• When DTC is activated by CMIA interrupt while DISEL bit of MRB in DTC is 0
[Setting condition]
Set when TCNT matches TCORA
Bit 5—Timer Overflow Flag (OVF): Status flag indicating that TCNT has overflowed (changed
from H'FF to H'00).
Bit 5
OVF
0
1
Description
[Clearing condition]
• Cleared by reading OVF when OVF = 1, then writing 0 to OVF
[Setting condition]
Set when TCNT overflows from H'FF to H'00
