trigger signal. If ADEN in ADCSRA is set, this will start a conversion. Switching to Free Running
mode (ADTS[2:0]=0) will not cause a trigger event, even if the ADC Interrupt Flag is set
Table 13-4.
When an ADC conversion is complete, the result is found in the ADC register.
• Bits 7:0 – ADC7:0: ADC Conversion Result
These bits represent the result from the conversion.
• Bits 7:4 – Res: Reserved Bit
These bits are reserved and will always read zero.
• Bits 3:0 – ADC3D..ADC0D: ADC3..0 Digital Input Disable
When this bit is written logic one, the digital input buffer on the corresponding ADC pin is dis-
abled. The corresponding PIN register bit will always read as zero when this bit is set. When an
analog signal is applied to the ADC3..0 pin and the digital input from this pin is not needed, this
bit should be written logic one to reduce power consumption in the digital input buffer.
