CMFA

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 with

the transfer counter not being 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

Description

[Clearing condition]

(Initial value)

Cleared by reading OVF when OVF = 1, then writing 0 to OVF

[Setting condition]

Set when TCNT overflows from H'FF to H'00
