Technical Data
190
Address:
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.
FOC[1:5] — Force Output Comparison Bit
Bits [2:0] — Unimplemented

Read:
Write:
When the FOC bit associated with an output compare circuit is set,
the output compare circuit immediately performs the action it is
programmed to do when an output match occurs.
Always read 0
0 = Not affected
1 = Output x action occurs
