The minimum pulse length depends on the external circuit.  If the PIC output
is driving a single 74HC input via a reasonably short wire on the same board
(like into the clock input of a flip-flop), then 200nS is plenty.  More
capacitance requires a longer pulse to compensate for the slower rise time.
