    TECHNICAL DATA
    All TOCx register pairs reset to ones ($FFFF).
    9.3.2 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 be-
    tween 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 pro-
    grammed 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
    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.
    0 = Not affected
    1 = Output x action occurs
    Bits [2:0] — Not implemented
    Always read zero
    9.3.3 Output Compare Mask Registers
    Use OC1M with OC1 to specify the bits of port A that are affected by a successful OC1
    compare. The bits of the OC1M register correspond to PA[7:3].
