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

The IIO current sunk must always respect the absolute maximum rating specified in Table 58: Current characteristics 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 58: Current characteristics

and the sum of IIO (I/O ports and control pins) must not exceed IVDD.

Not tested in production, based on characterization results.
