21.0
There are two independent voltage references
available:
• Programmable Voltage Reference
• 1.024V Fixed Voltage Reference
21.1
The Voltage Reference module provides an internally
generated voltage reference for the comparators and
the DAC module. The following features are available:
• Independent from Comparator operation
• Single 32-level voltage ranges
• Output clamped to V
• Ratiometric with V
• 1.024V Fixed Reference Voltage (FVR)

always return a ‘0’.
Due to the limited current drive capability, a buffer must
be used on the voltage reference output for external
connections to CV
buffering technique.

The

REFCON1 register will enable the voltage reference by
allowing current to flow in the V
When the D1EN bit is cleared, current flow in the V
voltage divider is disabled minimizing the power drain

When the device wakes up from Sleep through an
interrupt or a Watchdog Timer time-out, the contents of
the RECON1 register are not affected. To minimize
current consumption in Sleep mode, the voltage
