That gives you 4 cycles per pulse.  You could speed it up by unrolling th=
e
loop:
loop    BSF _pin
        BCF _pin
        BSF _pin
        BCF _pin
        GOTO loop
would give you 2 pulses per 6 cycles, for example.  Adding more BSF/BCF's=

inside the loop will asymptotically approach 2 cycles per pulse.

If you need faster pulses than that, try a PWM channel - I think you can
get a pulse per cycle that way, with no software overhead once started. =

You may also be able to use the SSP or USART module to send 0x55's
continuously, but I don't know if the baud rate can be set high enough in=

any suitable mode.
