Description
Compare-Match Flag B
[Setting condition]
When the values of TCNT_Y and TCORB_Y match
[Clearing conditions]
Compare-Match Flag A
[Setting condition]
When the values of TCNT_Y and TCORA_Y match
[Clearing conditions]
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
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
Read CMFB when CMFB = 1, then write 0 in CMFB
When the DTC is activated by a CMIB interrupt
Read CMFA when CMFA = 1, then write 0 in CMFA
When the DTC is activated by a CMIA interrupt
