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.
Description
Voltage Reference Level Select High Bit
In conjunction with the Low bit (REFSELL) in ADC Control Register 0, this determines
the level of the internal voltage 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.
Reserved
These bits are reserved and must be programmed to 0000.
Input Buffer Mode Select
000 = Single-ended, unbuffered input.
001 = Single-ended, buffered input with unity gain.
010 = Reserved.
011 = Reserved.
100 = Differential, unbuffered input.
101 = Differential, buffered input with unity gain.
110 = Reserved.
111 = Reserved.
