;   This file is a basic code template for assembly code generation   *
;   on the PICmicro PIC12C508A. This file contains the basic code     *
;   building blocks to build upon.                                    *

;   If the internal RC oscillator is not implemented then the first   *
;   instruction after the ORG 0x000 directive is not required.        *
