The purpose of this application note is to design a clock
while multiplexing the features as much as possible,
allowing the circuit to use the 18-pin PIC16C54. Other
devices in the Microchip line expand on this part, making
it a good starting point for learning the basics. This
design is useful because it utilizes every pin for output
and switches some of them to inputs briefly to read the
keys. For a more extensive clock design, consult application
note AN529.
