1.
The IIO current sunk must always respect the absolute maximum rating specified in Section 13.2 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 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.
3.
The minimum VOH value (with IIO=-10mA) depends on the chosen device type. For Flash devices, min = VDD - 1.3 V and
for ROM devices, min = VDD - 1.7 V
