Subject to general operating conditions for VDD, fCPU, and TA unless otherwise specified.

The IIO current sunk must always respect the absolute maximum rating specified in Section 20.2 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 Section 20.2 and the sum of IIO (I/O

ports and control pins) must not exceed IVDD.

Not tested in production, based on characterization results.
