2.3.4
Most appliances that have a LCD show a clock readout when the appliance is not in
use. In this project, Timer1 is used to create a real-time clock readout on the LCD.
Objectives
1. Configure the PIC16F917 to use the 32.768 kHz crystal to clock Timer1.
2. Convert Timer1 into seconds, minutes and hours.

Note:
Project 4: Digital Clock Using Timer1
Crystal circuits are very sensitive to noise and stray capacitances. In
general, the traces between a crystal and a microcontroller should be as
short as possible. The reason the PICDEM Mechatronics Demo Board
strayed from good design practice was to give you the option to use pins
RA7 and RA6 for other functions.
