I/O ports
Caution: The alternate function must not be activated as long as the pin is configured as input with
interrupt, in order to avoid generating spurious interrupts.
Analog alternate function
When the pin is used as an ADC input, the I/O must be configured as floating input. The
analog multiplexer (controlled by the ADC registers) switches the analog voltage present on
the selected pin to the common analog rail which is connected to the ADC input.
It is recommended not to change the voltage level or loading on any port pin while
conversion is in progress. Furthermore it is recommended not to have fast toggling pins
located close to a selected analog pin.
Warning: The analog input voltage level must be within the limits
t(s) stated in the absolute maximum ratings.

Unused I/O pins
Unused I/O pins must be connected to fixed voltage levels. Refer to Section 12.8.
Low power modes

Mode
Description
Wait
No effect on I/O ports. External interrupts cause the device to exit from wait mode.
Halt
No effect on I/O ports. External interrupts cause the device to exit from halt mode.
Interrupts
The external interrupt event generates an interrupt if the corresponding configuration is
selected with DDR and OR registers and the interrupt mask in the CC register is not active
(RIM instruction).
