Condition/Note
Calibrated low power RC oscillator frequency is
f_XOSC / 750
Frequency drift when temperature changes after
calibration
Frequency drift when supply voltage changes after
calibration
When the low power RC oscillator is enabled,
calibration is continuously done in the background
as long as the high speed crystal oscillator is
running.

The HS RCOSC will be calibrated once when the
high speed crystal oscillator is selected as system
clock source (CLKCON.OSC is set to 0), and also
when the system wakes up from PM{1-3}. See
13.1.5.1 for details).
