Description
[Clearing condition]
Read OVF0 when OVF0 =1, then write 0 in OVF0
[Setting condition]
TCNT0 overflowed from H'FFFFFFFF to H'00000000
[Clearing condition]
Read ICF0D when ICF0D =1, then write 0 in ICF0D
[Setting condition]
TCNT0 value is transferred to input capture register
ICR0D by an input capture signal
[Clearing condition]
Read ICF0C when ICF0C =1, then write 0 in ICF0C
[Setting condition]
TCNT0 value is transferred to input capture register
ICR0C by an input capture signal
[Clearing conditions]
1. Read ICF0B when ICF0B =1, then write 0 in ICF0B
2. When cleared by the DMAC in data transfer
[Setting condition]
TCNT0 value is transferred to input capture register
ICR0B by an input capture signal
[Clearing condition]
Read ICF0A when ICF0A =1, then write 0 in ICF0A
[Setting condition]
TCNT0 value is transferred to input capture register
ICR0A by an input capture signal
