The ADC Control/Status Register 1 (ADCCTL1) configures the input buffer stage,
enables the threshold interrupts and contains the status of both threshold triggers. It is also
used to select the voltage reference configuration.
REFSELH—Voltage Reference Level Select High Bit; in conjunction with the Low bit
(REFSELL) in
reference; the following details the effects of {REFSELH, REFSELL}; this reference is
independent of the Comparator reference.
00= Internal Reference Disabled, reference comes from external pin
01= Internal Reference set to 1.0 V
10= Internal Reference set to 2.0 V (default)
11= Reserved

The ADC Data High Byte (ADCD_H) register contains the upper eight bits of the ADC
output. The output is an 13-bit two’s complement value. During a single-shot conversion,
this value is invalid. Access to the ADC Data High Byte register is read-only. Reading the
ADC Data High Byte register latches data in the ADC Low Bits register.
