Output from the oscillator amplifier.
VDDA

-
Analog 3.3 V pad supply voltage: This should be
nominally the same voltage as VDD but should be isolated
to minimize noise and error. This voltage is used to power
the ADC. This pin should be tied to 3.3 V if the ADC are
not used.
VREFN
48
-
ADC negative reference voltage: This should be
nominally the same voltage as VSS but should be isolated
to minimize noise and error. Level on this pin is used as a
reference for ADC.
