Analog alternate function
Configure the I/O as floating input to use an ADC input. The analog multiplexer (controlled
by the ADC registers) switches the analog voltage present on the selected pin to the
common analog rail, connected to the ADC input.
Analog Recommendations
Do not change the voltage level or loading on any I/O while conversion is in progress. Do not
have clocking pins located close to a selected analog pin.
The analog input voltage level must be within the limits stated in the absolute maximum
ratings.
I/O port implementation
The hardware implementation on each I/O port depends on the settings in the DDR and OR
registers and specific I/O port features such as ADC input or open drain.
Switching these I/O ports from one state to another should be done in a sequence that
prevents unwanted side effects. Recommended safe transitions are illustrated in
Other transitions are potentially risky and should be avoided, since they may present
unwanted side-effects such as spurious interrupt generation.
