Welcome back!

Rather than spoiling the fun for everyone, I shaved one cycle
off of the 'toascii' routine. There are no comments, so the 'hint'
is only partially revealed.

; 5 instructions words, 6 cycles:
toascii
        ADDLW   -0x0a
        SKPNC
         ADDLW  'A'-'9' - 1
        ADDLW   '0' + 0x0a
        RETURN
