REAL TIME CLOCK (RTC)
Most hardware projects need a real time clock or a delay source. For this reason, the dsPICPRO4
development board is provided with PCF8583P. It is a Real Time Clock Chip that uses I
2
C seri-
al communication to exchange data with the microcontroller and has one interrupt output. In
order that it works properly, both interrupt and I
2
C communication lines must be connected to
the microcontroller by using switch 8 of the DIP switch SW2 and switches 7 and 8 of the DIP
switch SW4.
