• Bits 7:0 – ADC7D:ADC0D: Digital Input Disable
When this bit is written logic one, the digital input buffer on the corresponding ADC pin
is disabled. 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.
Reserved for future use.
• Bit 7:0 – ADC15D:ADC8D - Reserved Bits
This bit is reserved for future use. For ensuring compatibility with future devices, this bit
must be written to zero.
This register contains the calibration values of the reference voltage of the ADC. The
values are loaded from the fuse memory after power-up. They can be corrected by the
application software e.g. to compensate for temperature changes. The internal 1.6V
reference voltage is calibrated and has therefore the highest accuracy compared to the
1.5V or AVDD reference.
• Bit 7 – Res - Reserved Bit
This bit is reserved for future use. A read access always will return zero. A write access
does not modify the content.
