The DCB bits (OCxCON2<10:9>) provide for resolution
better than one instruction cycle. When used, they
delay the falling edge generated by a match event by a
portion of an instruction cycle.
For example, setting DCB<1:0> = 10 causes the falling
edge to occur half way through the instruction cycle in
which the match event occurs, instead of at the
beginning.
OCM<2:0> = 001. When operating the module in PWM
mode (OCM<2:0> = 110 or 111), the DCB bits will be
double-buffered.

The DCB bits are intended for use with a clock source
identical to the system clock. When an OCx module
with enabled prescaler is used, the falling edge delay
caused by the DCB bits will be referenced to the
system clock period, rather than the OCx module's
period.
