Clock Generator
Description
Slow Clock Crystal Oscillator
Slow Clock RC Oscillator
Main Oscillator
The Clock Generator is made up of
32,768 Hz low-power Oscillator.
It provides the following clocks:
The Clock Generator User Interface is embedded within the Power Management Controller one
and is described in
CKGR_.
The Clock Generator integrates a 32,768 Hz low-power oscillator. The XIN32 and XOUT32 pins
must be connected to a 32,768 Hz crystal. Two external capacitors must be wired as shown in
Figure
The user has to take into account the possible drifts of the RC Oscillator. More details are given
in the section “DC Characteristics” of the product datasheet.
