Sorry but which LFSR? The simple LFSR in the PIClist
archive does not seem to do this.

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

Regards,
Xiaofan

The common LFSR pseudo-random generators in fact generate one bit per
step. Just take the number of bits you need.
