Notes:
1. The IIO current sunk must always respect the absolute maximum rating specified in Section 13.2.2 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 13.2.2 and the sum of
IIO (I/O ports and control pins) must not exceed IVDD. True open drain I/O pins does not have VOH.
