Description
Output Select 1 and 0
These bits select a method of TMO pin output
when compare match A of TCORA and TCNT
occurs.
00: No change when compare match A occurs
01: 0 is output when compare match A occurs
10: 1 is output when compare match A occurs
11: Output is inverted when compare match A
occurs (toggle output)

Cleared by reading OVF when OVF = 1, then
writing 0 to OVF
Set when TCNT matches TCORB
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
Set when TCNT matches TCORA
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
