Figure 10-1. Clock system overview
Each clock source is briefly described in the following sub-sections.
10.3
Clock Options
10.3.1
32 kHz Ultra Low Power Internal Oscillator
The 32 kHz Ultra Low Power (ULP) Internal Oscillator is a very low power consumption clock
source. It is used for the Watchdog Timer, Brown-Out Detection and as an asynchronous clock
source for the Real Time Counter. This oscillator cannot be used as the system clock source,
and it cannot be directly controlled from software.
10.3.2
32.768 kHz Calibrated Internal Oscillator
The 32.768 kHz Calibrated Internal Oscillator is a high accuracy clock source that can be used
as the system clock source or as an asynchronous clock source for the Real Time Counter. It is
calibrated during production to provide a default frequency which is close to its nominal
frequency.
