• TCSR_1
Bit Bit Name Initial Value R/W Description
7
CMFB 0
R/(W)* Compare-Match Flag B
[Setting condition]
When the values of TCNT_1 and TCORB_1 match
[Clearing conditions]
• Read CMFB when CMFB = 1, then write 0 in CMFB
• When the DTC is activated by a CMIB interrupt
6
CMFA 0
R/(W)* Compare-Match Flag A
[Setting condition]
When the values of TCNT_1 and TCORA_1 match
[Clearing conditions
• Read CMFA when CMFA = 1, then write 0 in CMFA
• When the DTC is activated by a CMIA interrupt
5
OVF
0
R/(W)* Timer Overflow Flag
[Setting condition]
When TCNT_1 overflows from H'FF to H'00
[Clearing condition]
Read OVF when OVF = 1, then write 0 in OVF

R/W These bits specify how the TMO1 pin output level is to be
changed by compare-match B of TCORB_1 and
TCNT_1.
00: No change
01: 0 is output
