R/(W)^* Input Capture Interrupt Flag
A function of channel 2 only: the flag is set when
input capture is requested via the TCLK pin.
0: No input capture request has been issued.
[Clearing condition]
0 is written to ICPF

pin.
[Setting condition]
When an input capture is requested via the TCLK
pin
0
R/(W)^* Underflow Flag
Status flag that indicates occurrence of a TCNT_2
underflow.
0: TCNT_2 has not underflowed
[Clearing condition]
0 is written to UNF
1: TCNT_2 has underflowed
[Setting condition]
TCNT_2 underflows
