I/O ports

Doc ID 12468 Rev 3

75/279

Warning:

The analog input voltage level must be within the limits

stated in the absolute maximum ratings.

8.3

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 Figure 33.

Other transitions are potentially risky and should be avoided, since they are likely to present

unwanted side-effects such as spurious interrupt generation.
