;   This file is a basic code template for object module code         *
;   generation on the PICmicro rfPIC12C509AF. This file contains the  *
;   basic code building blocks to build upon.  As a project minimum   *
;   the 12C509AF.lkr file will also be required for this file to      *
;   correctly build. The .lkr files are located in the MPLAB          *
