DIDR0 – Digital Input Disable Register 0
DIDR1 – Digital Input Disable Register 1
Table 15-6.
• Bits 7:4,2:0 – ADC6D:ADC0D: ADC6:0 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.
• Bit 3 – AREFD: AREF Digital Input Disable
When this bit is written logic one, the digital input buffer on the AREF pin is disabled. The corre-
sponding PIN register bit will always read as zero when this bit is set. When an analog signal is
applied to the AREF 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 7:4 – ADC10D:ADC7D: ADC10:7 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 ADC10:7 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.
