0x0
Takes two samples with opposite GP_ADC_SIGN to cancel
the internal offset voltage of the ADC; Highly recommended
for DC-measurements.

GP_ADC_MUTE
Takes sample at mid-scale (to dertermine the internal offset
and/or noise of the ADC with regards to VDD_REF which is
also sampled by the ADC).

GP_ADC_SEL
ADC input selection which must be set before the
GP_ADC_START bit is enabled.
If GP_ADC_SE = 1 (single ended mode):
0000 = P0[0]
0x0
0001 = P0[1]
0010 = P0[2]
0011 = P0[3]
0100 = AVS
0101 = VDD_REF
0110 = VDD_RTT
0111 = VBAT3V
1000 = VDCDC
1001 = VBAT1V
All other combinations are reserved.
If GP_ADC_SE = 0 (differential mode):
0000 = P0[0] vs P0[1]
All other combinations are P0[2] vs P0[3].
