22.10.2 Bit 4: 0 – MUX[4:0]: ADC Channel Selection Bits

These 4 bits determine which analog inputs are connected to the ADC input. The different set-

ting are shown in Table 22-5.

If these bits are changed during a conversion, the change will not take effect until this conversion

is complete (it means while the ADIF bit in ADCSRA register is set).

22.10.3 ADCSRA – ADC Control and Status Register A

• Bit 7 – ADEN: ADC Enable Bit

Set this bit to enable the ADC.

Clear this bit to disable the ADC.

Clearing this bit while a conversion is running will take effect at the end of the conversion.
