4.3.3 RTC oscillator
point, software can control switching to the main oscillator as a clock source. Prior to
starting the main oscillator, a frequency range must be selected by configuring the
OSCRANGE bit in the SCS register.
The RTC oscillator provides a 1 Hz clock to the RTC and a 32 kHz clock output that can
be used as the clock source for PLL0 and CPU and/or the watchdog timer.
Remark: The RTC oscillator must not be used as a clock source when the PLL0 output is
selected to drive the USB controller. In this case select the main oscillator as clock source
for PLL0 (see also
