Input capture/compare match flag A0
[Clearing conditions]
(Initial value)
0 ^{• Read IMFA0 when IMFA0=1, then write 0 in IMFA0}
• DMAC activated by IMIA0 interrupt.
[Setting conditions]
• TCNT0=GRA0 when GRA0 functions as an output
1 _{compare register.}
• TCNT0 value is transferred to GRA0 by an input capture
signal when GRA0 functions as an input capture register.
Input capture/compare match flag A1
[Clearing conditions]
(Initial value)
0 • Read IMFA1 when IMFA1=1, then write 0 in IMFA1
• DMAC activated by IMIA1 interrupt.
[Setting conditions]
• TCNT1=GRA1 when GRA1 functions as an output
1 ^{compare register.}
• TCNT1 value is transferred to GRA1 by an input capture
signal when GRA1 functions as an input capture register.
Input capture/compare match flag A2
[Clearing conditions]
(Initial value)
0 • Read IMFA2 when IMFA2=1, then write 0 in IMFA2
• DMAC activated by IMIA2 interrupt.
[Setting conditions]
• TCNT2=GRA2 when GRA2 functions as an output
1 compare register.
• TCNT2 value is transferred to GRA2 by an input capture
signal when GRA2 functions as an input capture register.
Input capture/compare match interrupt enable A0
0 IMIA0 interrupt requested by IMFA0 flag is disabled
1 IMIA0 interrupt requested by IMFA0 is enabled
(Initial value)
Input capture/compare match interrupt enable A1
0 IMIA1 interrupt requested by IMFA1 flag is disabled
1 IMIA1 interrupt requested by IMFA1 is enabled
(Initial value)
Input capture/compare match interrupt enable A2
0 IMIA2 interrupt requested by IMFA2 flag is disabled
1 IMIA2 interrupt requested by IMFA2 is enabled
(Initial value)
Note: * Only 0 can be written, to clear the flag.
