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.
The TOF bit can be used with interrupt generation in order to measure events that go
beyond the timer range (FFh).

Output compare
In this section, the index, i, may be 1 or 2 because there are two output compare functions in
the 8-bit timer.
This function can be used to control an output waveform or indicate when a period of time
has elapsed.
When a match is found between the Output Compare register and the free running counter,
the output compare function:
●
●
●
Two 8-bit registers Output Compare Register 1 (OC1R) and Output Compare Register 2
(OC2R) contain the value to be compared to the counter register each timer clock cycle.
Assigns pins with a programmable value if the OCiE bit is set
Sets a flag in the status register
Generates an interrupt if enabled
