(2)

Output high level voltage for an I/O pin

when 4 pins are sourced at same time

(see Figure 144)

The IIO current sunk must always respect the absolute maximum rating specified in Section 12.2.2: Current characteristics

on page 314 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 12.2.2: Current
