Electrical characteristics

1. I/O can be left unconnected if it is configured as output (0 or 1) by the software. This has the advantage of

greater EMC robustness and lower cost.

1. The IIO current sunk must always respect the absolute maximum rating specified in Section 12.2.2 and the sum of IIO (I/O

ports and control pins) must not exceed IVSS.

2. The IIO current sourced must always respect the absolute maximum rating specified in Section 12.2.2 and the sum of IIO

(I/O ports and control pins) must not exceed IVDD. True open drain I/O pins do not have VOH.
