AUXADC measurement frequency in
Continuous mode
000 = 1Hz
001 = 4Hz
010 = 8Hz
011 = 16Hz
100 = 32Hz
101 = 64Hz
110 = 128Hz

Reset by state machine.
Configure AUX3 input to be the VREF supply
for AUXADC calibration.
0 = AUX3 input connected to AUX3 pin
1 = AUX3 input connected to unbuffered
VREF
Reset by state machine.
Enable for AUXADC bandgap (VREF) buffer.
0 = AUXADC REFBUF is only enabled
during conversions that use the VREF as a
reference
1 = AUXADC REFBUF is always enabled
when the AUXADC is enabled
Reset by state machine.
Whether the old data must be read before
new conversions can be made
0 = No effect (new conversions overwrite
old)
1 = New conversions are held back (and
measurements delayed) until AUX_DATAn
has been read.
Reset by state machine.
AUX1 input select:
00 = Off
01 = Input divided by 1
10 = Input divided by 2
11 = Input divided by 4
AUX1 reference select
0 = AUX1 measured relative to VRTC
1 = AUX1 measured relative to VREF
reference:
000 = 0V
FFF = measured voltage after divide
matches reference
