Atmel ATmega16/32/64/M1/C1
ADC Control and Status Register A – ADCSRA
• Bit 4, 2, 1, 0 – MUX4, MUX3, MUX2, MUX1, MUX0: 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 18-5.
If these bits are changed during a conversion, the change will not take effect until this conver-
sion is complete (it means while the ADIF bit in ADCSRA register is set).
Bit
Read/Write
Initial Value
• 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.
