1. The active edge is the rising edge.
2. The time between an event on the ICAPi pin and the appearance of the corresponding flag is from 2 to 3 CPU clock cycles.

This depends on the moment when the ICAP event happens relative to the timer clock.

the user toggle the output pin and if the ICIE bit is set. This can be avoided if the input
capture function i is disabled by reading the ICiHR (see note 1).
The TOF bit can be used with interrupt in order to measure event that go beyond the timer
range (FFFFh).
