DIDR0 – Digital Input Disable Register 0
• Bits 7:2 – Reserved
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 1:0 – PA1DID:PA0DID: Digital Input Disable
When this bit is written logic one, the digital input buffer on the corresponding Port A 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 PA1:0 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.
