////  This program is an example application program that can be       ////
////  be loaded, recompiled and reloaded by a stand alone bootloader.  ////
////                                                                   ////
////  Before loading this program the bootloader (ex_bootloader.c)     ////
////  must be compiled and loaded into the target chip.                ////
////                                                                   ////
////  Use an RS232 link and the SIOW.EXE program to load this HEX file ////
////  into the target chip.  See ex_bootloader.c for more information. ////
////                                                                   ////

////     PCM,PCH    pin C7 to RS232 RX, pin C6 to RS232 TX             ////
////                                                                   ////
////  This example will work with the PCM and PCH compilers.  The      ////
////  following conditional compilation lines are used to include a    ////
////  valid device for each compiler.  Change the device, clock and    ////
////  RS232 pins for your hardware if needed.                          ////
