//// This program demonstartes the watchdog timer. If the user ////
//// does not hit a key in the set amount of time, the processor ////
//// restarts, and tells the user why it restarted. ////

//// Jumpers: ////
//// PCH pin C7 to RS232 RX, pin C6 to RS232 TX ////
//// PCD none ////

//// This example will work with the PCD compiler. ////
//// 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. ////
