EXTREF
EXTREF = 1 selects an external reference voltage connected to REFIN(+), REFIN() for the voltage input or the
VDD monitor.
EXTREF = 0 selects the on-chip internal reference. The internal reference must be used with the internal
temperature sensor for proper operation.
3 to 2
These bits must be 0 for proper operation.
1
VTSHORT
VTSHORT = 1 internally shorts the voltage/temperature channel input for test purposes.
0
VTCHOP = 1
VTCHOP = 1 sets internal chopping on the voltage/temperature channel.
The VTCHOP bit must be set to 1 for the specified voltage/temperature channel performance.
