DIDR0 – Digital Input Disable Register 0
DIDR1 – Digital Input Disable Register 1
Table 4-60.
• Bits 7:0 – ADC7D:ADC0D: ADC7:0 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 ADC7:0 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.
• Bits 7:3 - Reserved Bits
These bits are reserved for future use. For compatibility with future devices, they must be written
to zero when DIDR1 is written.
• Bits 2..0 – ADC10D..ADC8D: ADC10..8 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 ADC10:8 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.
