ADC Data High Byte Register
The ADC Data High Byte register contains the upper eight bits of the 10-bit ADC output.
During a conversion, this value is invalid. Access to the ADC Data High Byte register is
read-only. The full 10-bit ADC result is given by {ADCD_H[7:0], ADCD_L[7:6]}.

ADCD_H—ADC Data High Byte
This byte contains the upper eight bits of the 10-bit ADC output. These bits are not valid
during a conversion. These bits are undefined after a Reset.
ADC Data Low Bits Register
The ADC Data Low Bits register contains the lower two bits of the conversion value. Dur-
ing a conversion this value is invalid. Access to the ADC Data Low Bits register is read-
only. The full 10-bit ADC result is given by {ADCD_H[7:0], ADCD_L[7:6]}.

ADCD_L—ADC Data Low Bits
These are the least significant two bits of the 10-bit ADC output. During a conversion, this
value is invalid. These bits are undefined after a Reset.
Reserved
These bits are reserved and are always undefined.
