The IIO current sunk must always respect the absolute maximum rating specified in Section 20.2.2:

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

Output low level voltage for a standard

I/O pin when eight pins are sunk at same

time

(see Figure 129)

IIO =+5 mA

Output low level voltage for a high sink

I/O pin when four pins are sunk at same

time

(see Figure 130 and Figure 133)

IIO =+20 mA,

The IIO current sourced must always respect the absolute maximum rating specified in Section 20.2.2:

Current characteristics 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.
