VDDA Select Header (W2)

Jumper header W2 selects the MPB VDDA power source: either MPB power
(VDDI) or an external source. The drawing below shows the factory
configuration: a cut-trace short between pins 1 and 2. This configuration connects
filtered VDDI to VDDA.

To use an external power source, remove the cut-trace short from W2 pins 1 and
2, then connect the external power source to W2 pin 2. Removal of the cut-trace
short isolates the MCU VDDA pin from the other MPB circuitry. Isolation lets
you connect a precision VDDA source for accurate 10-bit analog/digital (A/D)
generation. When connecting an external VDDA power supply to the MPB,
connect the power supply ground to insertion point E1. For more information on
A/D generation refer to the Analog-To-Digital Converter Reference Manual,
ADCRM/AD.

NOTES

If the cut-trace short has been cut, you must install a fabricated
jumper on W2 to return it to the factory configuration.

Jumper header W2 is not populated by the factory.
