/* Demonstration of Rtc_Pcf8563 Set Time.
* Set the clock to a time then loop over reading time and
* output the time and date to the serial console.
*
* I used a RBBB with Arduino IDE, the pins are mapped a
* bit differently. Change for your hw
* SCK - A5, SDA - A4, INT - D3/INT1
*
* After loading and starting the sketch, use the serial monitor
* to see the clock output.
*
* setup: see Pcf8563 data sheet.
* 1x 10Kohm pullup on Pin3 INT
* No pullups on Pin5 or Pin6 (I2C internals used)
* 1x 0.1pf on power
* 1x 32khz chrystal
*
