2.6 32.768 KHz Oscillator

A 32.768 KHz oscillator is provided for use as a clock source for the real-time clock/calendar (RTCC) peripheral in

the PIC32MX796 microcontroller on the Max32 board. The output of this oscillator connects to pin 12 or connector

J11.

On the Max32 board, this signal connects to signal RC13, which connects to pin 73 on the PIC32 microcontroller.

This pin provides the secondary oscillator input, which can be used to clock the RTCC in the PIC32 microcontroller.
