ATmega169V/L

2514A–AVR–08/02

• Bits 4:0 – MUX4:0: Analog Channel Selection Bits

The value of these bits selects which combination of analog inputs are connected to the

ADC. See Table 90 for details. If these bits are changed during a conversion, the

change will not go in effect until this conversion is complete (ADIF in ADCSRA is set).
