Bit Bit Name
Initial
Value R/W Description
7 CMFB 0 R/(W)*
1
Compare-Match Flag B
[Setting condition]
When the values of TCNT_Y and TCORB_Y match
[Clearing condition]
Read CMFB when CMFB = 1, then write 0 in CMFB
6 CMFA 0 R/(W)*
1
Compare-Match Flag A
[Setting condition]
When the values of TCNT_Y and TCORA_Y match
[Clearing condition]
Read CMFA when CMFA = 1, then write 0 in CMFA
5 OVF 0 R/(W)*
1
Timer Overflow Flag
[Setting condition]
When TCNT_Y overflows from H'FF to H'00
[Clearing condition]
Read OVF when OVF = 1, then write 0 in OVF
4 ICIE 0 R/W Input Capture Interrupt Enable
Enables or disables the ICF interrupt request (ICIX)
when the ICF bit in TCSR_X is set to 1.
0: ICF interrupt request (ICIX) is disabled
1: ICF interrupt request (ICIX) is enabled
