PIC Microcontoller Radix Math Method

Binary to ASCII, 16 bit to 3digits (0..999)

by Nikolai Golovchenko

;Binary to decimal conversion (0..999)
;Input: NumH:NumL
;Output Hund:Tens:Ones
;If Input > 999 Output will roll over, e.g.
;for input=5678 output=678.
;Size: 34 instructions
;Execution  time  (max) including return:
;22+5*9-1+5*6-1+4*3-1+2 = 108 cycles
