1. The I_IO current sunk must always respect the absolute maximum rating specified in Table 19 and the sum of I_IO (I/O ports
and control pins) must not exceed I_VSS.
2. The I_IO current sourced must always respect the absolute maximum rating specified in Table 19 and the sum of I_IO (I/O
ports and control pins) must not exceed I_VDD. True open drain I/O pins does not have V_OH.
