4.2.4.1

OSC24M

This block implements an amplifier that when combined with a suitable quartz crystal and external load

capacitors implement an oscillator. The oscillator is powered from NVCC_PLL.

The system crystal oscillator consists of a Pierce-type structure running off the digital supply. A straight

forward biased-inverter implementation is used.

4.2.4.2

OSC32K

This block implements an amplifier that when combined with a suitable quartz crystal and external load

capacitors implement a low power oscillator. It also implements a power mux such that it can be powered

from either a ~3 V backup battery (VDD_SNVS_IN) or VDD_HIGH_IN such as the oscillator consumes
