Digital Input Disable Register 0 – DIDR0
Digital Input Disable Register 2 – DIDR2
Table 24-6.
• Bit 7:4, 1:0 – ADC7D..4D - ADC1D..0D : ADC7:4 - ADC1:0 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..4 / ADC1..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.
• Bit 5:0 – ADC13D..ADC8D: ADC13:8 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 ADC13..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.
