The ADC Data High Byte register
ADC output. During a single-shot 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]}. Reading the ADC Data High Byte register latches data
in the ADC Low Bits register.
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 single-shot conversion. During a continuous conversion, the last conversion out-
put is held in this register. These bits are undefined after a Reset.
The ADC Data Low Bits register
value. The data in the ADC Data Low Bits register is latched each time the ADC Data
High Byte register is read. Reading this register always returns the lower two bits of the
conversion last read into the ADC High Byte register. 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]}.
