;   This file is a basic code template for object module code         *
;   generation on the PICmicro PIC16F505. This file contains the      *
;   basic code building blocks to build upon.  As a project minimum   *
;   the 16F505.lkr file will also be required for this file to        *
;   correctly build. The .lkr files are located in the MPLAB          *  
;   directory.                                                        *
