AUXADC AUX3 input select
0 = Disable AUX3 measurement
1 = Enable AUX3 measurement
Reset by state machine.
AUXADC AUX2 input select
0 = Disable AUX2 measurement
1 = Enable AUX2 measurement
Reset by state machine.
AUXADC AUX1 input select
0 = Disable AUX1 measurement
1 = Enable AUX1 measurement
Reset by state machine.
AUXADC MASK input control
00 = MASK is ignored
01 = When MASK is asserted, all AUXADC
measurements are inhibited.
10 = Reserved
11 = MASK input initiates AUXADC
measurements. AUXADC_POLL and
AUXADC_CTC have no effect. MASK
polarity is controlled by GPn_CFG.
Reset by state machine.
AUXADC measurement frequency in
Continuous mode
000 = 1Hz
001 = 4Hz
010 = 8Hz
011 = 16Hz
100 = 32Hz
101 = 64Hz
110 = 128Hz
111 = 256Hz
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
