ADCL and ADCH – ADC Data Register
Table 4-53.
ADLAR = 0
ADLAR = 1
When an ADC conversion is complete, the result is found in these two registers.
When ADCL is read, the ADC Data Register is not updated until ADCH is read. Consequently,
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.
The ADLAR bit in ADCSRB, and the MUXn bits 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.
