16-bit timer registers
Each timer is associated with 3 control and status registers, and with 6 pairs of data
registers (16-bit values) relating to the 2 input captures, the 2 output compares, the counter
and the alternate counter.

OCIE
0: Interrupt is inhibited
1: A timer interrupt is generated whenever the ICF1 or ICF2 bit of the SR register is
set.
0: Interrupt is inhibited
1: A timer interrupt is generated whenever the OCF1 or OCF2 bit of the SR register
is set.
0: Interrupt is inhibited
1: A timer interrupt is enabled whenever the TOF bit of the SR register is set.
This bit is set and cleared by software.
0: No effect on the OCMP2 pin
1: Forces the OLVL2 bit to be copied to the OCMP2 pin, if the OC2E bit is set and
even if there is no successful comparison
