VOL 1)
Output low level voltage for a standard I/O pin
when 8 pins are sunk at same time
(see Figure 84 and Figure 87)
Output low level voltage for a high sink I/O pin
when 4 pins are sunk at same time
(see Figure 85 and Figure 88)
VOH 2)
Output high level voltage for an I/O pin
when 4 pins are sourced at same time
(see Figure 86 and Figure 89)

Notes:
1. The IIO current sunk must always respect the absolute maximum rating specified in Section 16.2.2 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 16.2.2 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.
