These bits are always read as 0. The write value should
always be 0.
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.
1: Input capture has been requested via the TCLK pin.
Note: * Contents do not change when 1 is written to
Underflow Flag
Status flag that indicates occurrence of a TCNT_2
underflow.
0: TCNT has not underflowed.
1: TCNT has underflowed.
Note: * Contents do not change when 1 is written to
Input Capture Control
A function of channel 2 only: determines whether the
input capture function can be used, and when used,
whether or not to enable interrupts.
When using this input capture function it is necessary to
set the TCLK pin to input mode with the TCOE bit in the
TOCR register. Additionally, use the CKEG bit to
designate use of either the rising or falling edge of the
TCLK pin to set the value of TCNT_2 in TCPR_2.
00: Input capture function is not used.
01: Reserved (Setting prohibited)
10: Input capture function is used. Interrupt due to ICPF
11: Input capture function is used. Interrupt due to ICPF
