Bit Bit Name
Initial
Value R/W Description
7 CMFB 0 R/(W)* Compare-Match Flag B
[Setting condition]
When the values of TCNT_X and TCORB_X match
[Clearing condition]
Read CMFB when CMFB = 1, then write 0 in CMFB
6 CMFA 0 R/(W)* Compare-Match Flag A
[Setting condition]
When the values of TCNT_X and TCORA_X match
[Clearing condition]
Read CMFA when CMFA = 1, then write 0 in CMFA
5 OVF 0 R/(W)* Timer Overflow Flag
[Setting condition]
When TCNT_X overflows from H'FF to H'00
[Clearing condition]
Read OVF when OVF = 1, then write 0 in OVF
4 ICF 0 R/(W)* Input Capture Flag
[Setting condition]
When a rising edge and falling edge is detected in the
external reset signal in that order.
[Clearing condition]
Read ICF when ICF = 1, then write 0 in ICF
