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.

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).
