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 clocking pins located
close to a selected analog pin.
I/O port implementation
The hardware implementation on each I/O port depends on the settings in the DDR and OR
registers and specific feature of the I/O port such as ADC Input or true 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 are likely to present
unwanted side-effects such as spurious interrupt generation.

Low power modes
Table 30.
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).
Mode
Wait
Halt
Warning:
Effect of low power modes on I/O ports
No effect on I/O ports. External interrupts cause the device to exit from Wait mode.
No effect on I/O ports. External interrupts cause the device to exit from Halt mode.
The analog input voltage level must be within the limits
stated in the absolute maximum ratings.
