Read/Write
These bits are reserved for future use. To ensure compatibility with future devices, these
bits must be written to zero when ADCSRB is written.
If ADATE in ADCSRA is written to one, the value of these bits selects which source will
trigger an ADC conversion. If ADATE is cleared, the ADTS2:0 settings will have no effect.
A conversion will be triggered by the rising edge of the selected Interrupt Flag. Note that
switching from a trigger source that is cleared to a trigger source that is set, will generate a
positive edge on the 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
These bits are reserved for future use. To ensure compatibility with future devices, these
bits must be written to zero when DIDR0 is written.
When this bit is written logic one, the digital input buffer on the corresponding ADC pin is
disabled. The corresponding PIN Register bit will always read as zero when this bit is set.
When an analog signal is applied to the ADC5..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.
Note that ADC pins ADC7 and ADC6 do not have digital input buffers, and therefore do
not require Digital Input Disable bits.
