3.7.3.2 VREF Overview
This device includes a voltage reference (VREF) to supply an accurate 1.2 V or 2.1 V
voltage output.
The voltage reference can provide a reference voltage to external peripherals or a
reference to analog peripherals, such as the ADC, DAC, or CMP.
NOTE
PMC_REGSC[BGEN] bit must be set if the VREF regulator is
required to remain operating in VLPx modes.
NOTE
For either an internal or external reference if the VREF_OUT
functionality is being used, VREF_OUT signal must be
connected to an output load capacitor. Refer to the device data
sheet for more details.
