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.

Unused I/O pins
Unused I/O pins must be connected to fixed voltage levels. Refer to
Low power modes
Table 27.
Interrupts
The external interrupt event generates an interrupt if the corresponding configuration is
selected with DDR and OR registers and if the I bit in the CC register is cleared (RIM
instruction).
