Description
45 TEMP AO Temperature Sensor Voltage Output.
46 REFBUFIN AI/O Reference Input Voltage. The reference output and the reference buffer input.
47 PDREF DI This pin allows the choice of internal or external voltage references. When LOW, the on-chip reference
is turned on. When HIGH, the internal reference is switched off and an external reference must be
used.
48 PDBUF DI This pin allows the choice of buffering an internal or external reference with the internal buffer. When
LOW, the buffer is selected. When HIGH, the buffer is switched off.
