CKGR Block Diagram
Slow Clock Selection
SAM9G35
Figure 21-1. Clock Generator Block Diagram
The slow clock can be generated either by an external 32,768 Hz crystal or by the on-chip
32 kHz RC oscillator. The 32,768 Hz crystal oscillator can be bypassed by setting the bit
OSC32BYP to accept an external slow clock on XIN32.
The internal 32 kHz RC oscillator and the 32,768 Hz oscillator can be enabled by setting to 1,
respectively, RCEN bit and OSC32EN bit in the System Controller user interface. The OSCSEL
command selects the slow clock source.
