This bit is always read as 1 and cannot be modified.
Output Select 3 and 2
These bits specify how the timer output level is to be
changed by a compare-match B of TCORB and TCNT.
00: No change when compare-match B occurs
01: 0 is output when compare-match B occurs
10: 1 is output when compare-match B occurs
11: Output is inverted when compare-match B occurs
When TCNT = TCORB
Read CMFB when CMFB = 1, then write 0 in CMFB
DTC is activated by the CMIB interrupt and the DISEL
bit = 0 in MRB of DTC.
When TCNT = TCORA
Read CMFA when CMFA = 1, then write 0 in CMFA
DTC is activated by the CMIA interrupt and the DISEL
bit = 0 in MRB of DTC.
When TCNT overflows from H'FF to H'00
Read OVF when OVF = 1, then write 0 in OVF
