ADCL and ADCH – The ADC Data Register
ADLAR = 0
ADLAR = 1
• Bit 3 – ADIE: ADC Interrupt Enable
When this bit is written to one and the I-bit in SREG is set, the ADC Conversion Complete Inter-
rupt is activated.
• Bits 2:0 – ADPS2:0: ADC Prescaler Select Bits
These bits determine the division factor between the system clock frequency and the input clock
to the ADC.
Table 17-5.
• ADC9:0: ADC Conversion Result
These bits represent the result from the conversion, as detailed in
