ADCDH—ADC Data High Byte
This byte contains the upper eight bits of the ADC output. These bits are not valid during a
single-shot conversion. During a continuous conversion, the most recent conversion out-
put is held in this register. These bits are undefined after a Reset.
The ADC Data Low Byte (ADCD_L) register contains the lower bits of the ADC output
as well as an overflow status bit. The output is a 13-bit two’s complement value. During a
single-shot conversion, this value is invalid. Access to the ADC Data Low Byte register is
read-only. Reading the ADC Data High Byte register latches data in the ADC Low Bits
register.
ADCDL—ADC Data Low Bits
These bits are the least significant five bits of the 13-bits of the ADC output. These bits are
undefined after a Reset.
Reserved—Must be undefined.
OVF—Overflow Status
0= A hardware overflow did not occur in the ADC for the current sample.
1= A hardware overflow did occur in the ADC for the current sample, therefore the
current sample is invalid.
