AT43USB351M
3302E–USB–7/04
ADC Multiplexer Select Register – ADMUX
Bits 7..3
Res: Reserved Bits
These bits are reserved bits in the AT43USB351M and always read as zero.
Bits 3..0
MUX3..MUX0: Analog Channel Select Bits 3-0
The value of these three bits selects which analog input ADC11..0 is connected to the ADC.
See Table 23 for details.
If these bits are changed during a conversion, the change will not go into effect until this con-
version is complete (ADIF in ADCSR is set).
