15.13.6 DIDR0 – Digital Input Disable Register 0
z Bits 7:0 – ADC7D:ADC0D : ADC[7:0] Digital Input Disable
When an analog signal is applied to ADCn and the digital input of the pin is not needed, the ADCnD bit should be set to
reduce power consumption. Setting ADCnD disables the digital input buffer on the corresponding pin (ADCn). When
ADCnD is set the corresponding bit in the PINxn register will always read zero.
15.13.7 DIDR1 – Digital Input Disable Register 1
z Bits 7:0 – ADC15D:ADC8D : ADC[15:8] Digital Input Disable
When an analog signal is applied to ADCn and the digital input of the pin is not needed, the ADCnD bit should be set to
reduce power consumption. Setting ADCnD disables the digital input buffer on the corresponding pin (ADCn). When
ADCnD is set the corresponding bit in the PINxn register will always read zero.
15.13.8 DIDR2 – Digital Input Disable Register 2
z Bits 7:0 – ADC23D:ADC16D : ADC[23:16] Digital Input Disable
When an analog signal is applied to ADCn and the digital input of the pin is not needed, the ADCnD bit should be set to
reduce power consumption. Setting ADCnD disables the digital input buffer on the corresponding pin (ADCn). When
ADCnD is set the corresponding bit in the PINxn register will always read zero.
15.13.9 DIDR3 – Digital Input Disable Register 3
z Bits 27:24 – ADC27D:ADC24D : ADC[27:24] Digital Input Disable
When an analog signal is applied to ADCn and the digital input of the pin is not needed, the ADCnD bit should be set to
reduce power consumption. Setting ADCnD disables the digital input buffer on the corresponding pin (ADCn). When
ADCnD is set the corresponding bit in the PINxn register will always read zero.
