Description
Slow Clock Crystal Oscillator
Main Oscillator
The Clock Generator is made up of 2 PLL, a Main Oscillator, and a 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
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
