* The PCF2129AT is a CMOS Real Time Clock (RTC) and calendar with an integrated
* Temperature Compensated Crystal Oscillator and a 32.768 kHz quartz crystal
* optimized for very high accuracy and very low power consumption.
* Detailed Description:
* This simple example code has been written for the FRDM-KL25Z + OM13513
* boards and demonstrates how to set and read the time/date on the PCF2129AT
* using the SPI (do not forget to remove the JP1 jumper) interface.
*
* In this example the time to be set is Wednesday, February 8 2017, 2:45 PM.
*
* Connection: FRDM-KL25Z OM13513
* VDD J9-4 P2-2
* GND J9-18 P2-1
* MOSI J2-8 P2-5
* MISO J2-10 P2-6
* SCLK J2-12 P2-4
* CS J2-6 P2-7
