I used:
LFSR:   RLF     RANDOM,W
                 RLF     RANDOM,W
                 BTFSC   RANDOM,4
                 XORLW   1
                 BTFSC   RANDOM,5
                 XORLW   1
                 BTFSC   RANDOM,3
                 XORLW   1
                 MOVWF   RANDOM
                 RETLW   0

For extra confusion, TMR0 ran in the background with no prescaller.
Every time TMR0 interupted, I ran the above code and loaded RANDOM into
TMR0. When ever I needed a Random number, I load the value from TMR0.
You don't need to use TMR0 or interupt, it was free in this application
so I used it.
