DIDR0 – Digital Input Disable Register 0
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 23-5.
• Bits 7:6 – Res: Reserved Bits
These bits are reserved for future use. To ensure compatibility with future devices, these bits
must be written to zero when DIDR0 is written.
• Bit 5:0 – ADC5D..ADC0D: ADC5..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 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.
