10.2.1
When the Voltage Reference module is enabled, it will
require some time for the reference and its amplifier
circuits to stabilize. The user program must include a
small delay routine to allow the module to settle. See
Section 19.0 “Electrical Specifications” for the
minimum delay requirement.
