The IIO current sunk must always respect the absolute maximum rating specified in Table 52 and the sum of IIO (I/O ports and control pins)

must not exceed IVSS.

The IIO current sourced must always respect the absolute maximum rating specified in Table 52 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.

Not tested in production, based on characterization results.
