9.4.2 Timer Compare Force Register
The CFORC register allows forced early compares. FOC[1:5] correspond to the five output compares.
These bits are set for each output compare that is to be forced. The action taken as a result of a forced
compare is the same as if there were a match between the OCx register and the free-running counter,
except that the corresponding interrupt status flag bits are not set. The forced channels trigger their
programmed pin actions to occur at the next timer count transition after the write to CFORC.
The CFORC bits should not be used on an output compare function that is programmed to toggle its
output on a successful compare because a normal compare that occurs immediately before or after the
force can result in an undesirable operation.
