10. Voltage and Ground Reference Options
The voltage reference MUX is configurable to use an externally connected voltage reference, the on-chip
voltage reference, or one of two power supply voltages (see Figure 10.1). The ground reference MUX
allows the ground reference for ADC0 to be selected between the ground pin (GND) or a port pin dedi-
cated to analog ground (P0.1/AGND).
The voltage and ground reference options are configured using the REF0CN SFR described on page 62.
Electrical specifications are can be found in the Electrical Specifications Chapter.
Important Note About the V
inputs. When using an external voltage reference, P0.0/VREF should be configured as an analog input and
skipped by the Digital Crossbar. When using AGND as the ground reference to ADC0, P0.1/AGND should
be configured as an analog input and skipped by the Digital Crossbar. Refer to Section “23. Port Input/Out-
put” on page 138 for complete Port I/O configuration details. The external reference voltage must be within
the range 0 V
GND.
