19.3.6
TCPR2 is a 32-bit read-only register for use with the input capture function, provided only in
channel 2. The input capture function is controlled by means of the ICPE and CKEG bits in TCR2.
When input capture occurs, the TCNT2 value is copied into TCPR2. The value is set in TCPR2
only when the ICPF bit in TCR2 is 0.
