Bits 2:0 – MUX[2:0]: Analog Channel Selection Bits
The value of these bits selects which analog input is connected to the ADC, as shown in Table
16-4. Selecting channel ADC4 enables temperature measurement.
Notes:
1. After switching to internal voltage reference the ADC requires a settling time of 1ms before
measurements are stable. Conversions starting before this may not be reliable. The ADC must
be enabled during the settling time.
2. Due to the voltage divider present, a current will flow from VBAT to ground via a 100kΩ resistor
divider as long as this channel is selected.
If these bits are changed during a conversion, the change will not go into effect until this
conversion is complete (ADIF in ADCSRA is set).

ADCSRA – ADC Control and Status Register A
Bit 7 – ADEN: ADC Enable
Writing this bit to one enables the ADC. By writing it to zero, the ADC is turned off. Turning the
ADC off while a conversion is in progress, will terminate this conversion.
Bit 6 – ADSC: ADC Start Conversion
In Single Conversion mode, write this bit to one to start each conversion. In Free Running mode,
write this bit to one to start the first conversion. The first conversion after ADSC has been written
after the ADC has been enabled, or if ADSC is written at the same time as the ADC is enabled,
will take 25 ADC clock cycles instead of the normal 13. This first conversion performs initializa-
tion of the ADC.
ADSC will read as one as long as a conversion is in progress. When the conversion is complete,
it returns to zero. Writing zero to this bit has no effect.
Bit 5 – ADATE: ADC Auto Trigger Enable
