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.

3. Not tested in production, based on characterization results.
