I find that this makes a very effective test program.  You can easily tell
whether you're operating at the expected frequency just by measuring the
high time of the pulse on pin RB7.

T-highRB7 * 256 * 3 = f clock

I think.  I always forget if that formual is quite right.

 org 0x00
 nop
 nop
 nop
 nop
 nop
 bsf STATUS,RP0
 clrf TRISB
 bcf STATUS,RP0

loop incf PORTB,f
 goto loop

Well, hope that helps ya.
