////  This is a simple program used to demonstrate the use of the    ////
////  ICD as a device.  The example does some simple math and then   ////
////  flashes a LED at a frequency of 1Hz.                           ////
////                                                                 ////
////  Configure the CCS prototype card as follows:                   ////
////     Jumper from pin 42 to 47.                                   ////
////     See additional connections below.                           ////

////  This example will work with the PCM compiler.  The following   ////
////  conditional compilation lines are used to include a valid      ////
////  device for each compiler.  Change the device and clock for     ////
////  your hardware if needed.                                       ////
