Reserved (bits 7:2): Do not use.
GND_SEL (bit 1): Ground select control. This signal controls which ground reference is used in the
single-ended conversions.
1 = GSRN
0 = VSS (default)
ADC_DRDY (bit 0): Data ready flag. This read-only bit signals when valid data are ready in ADLO, ADHI
and ADMID.
1 = Valid data are ready
0 = Conversion in progress or ADC held in reset, ADC_DRDY goes low on the falling edge
of CONV
These store the result of the ADC data after conversion is complete. ADR0 is the LSB and ADR23 is the
MSB.
