• Bits 2..0 – ADPS2..0: ADC Prescaler Select Bits
These bits determine the division factor between the CK frequency and the input clock to the
ADC.
Table 47. ADC Prescaler Selections
When an ADC conversion is complete, the result is found in these two registers. The ADLAR bit
in ADMUX affect the way the result is read from the registers. If ADLAR is set, the result is left
adjusted. If ADLAR is cleared (default), the result is right adjusted. If the result is left adjusted
and no more than 8-bit precision is required, it is sufficient to read ADCH. Otherwise, ADCL
must be read first, then ADCH.
• ADC9..0: ADC Conversion Result
These bits represent the result from the conversion. For differential channels, this is the absolute
value after gain adjustment, as indicated in Table 46 on page 102. For single ended channels,
$000 represents analog ground, and $3FF represents the selected reference voltage minus one
LSB.
