; Title: Simple Addition Using Assembly
;---------------------
;Program Details:
; The purpose of this program is to load two bytes, Byte1 (F2H) and Byte2 (22H), in data registers REG0 and ; REG1, respectively and add the bytes.
; If the sum generates a carry, clear the data register REG2; otherwise, save the sum in REG2.

; Inputs: BYTE1 & BYTE 2
; Outputs: REG2
; Date: date and time
; Compiler: Simulator Version ????
; Author: name of the author
; Versions:
;           V1 - What is the version numer and what is the change for each version?
;           V2 - What is the version numer and what is the change for each version?
