After reading the ICiHR register, transfer of input capture data is inhibited and ICFi will never
be set until the ICiLR register is also read.
The ICiR register contains the free running counter value which corresponds to the most
recent input capture.
The two input capture functions can be used together even if the timer also uses the two
output compare functions.
In One pulse mode and PWM mode only Input Capture 2 can be used.
The alternate inputs (ICAP1 and ICAP2) are always directly connected to the timer. So any
transitions on these pins activates the input capture function.
Moreover if one of the ICAPi pins is configured as an input and the second one as an output,
an interrupt can be generated if the user toggles 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 generation in order to measure events that go
beyond the timer range (FFFFh).
