//
//  Description "FET410_RTCwLCD": This program maintains a real time clock and
//  displays the current time on a 3.5 digit static LCD. The colon between the
//  minutes and seconds toggles on or off each second to indicate that the clock
//  is running.  The digits of the display are only rewritten each minute once
//  the elapsed seconds roll over from 60 back to 0. The fourth digit is
//  automatically blank for hours 1-9. The software is totally interrupt driven.
//  It only comes out of low power mode 3 and executes code when a Basic Timer
//  interrupt occurs, once each second.
