V_OL ¹⁾
Output low level voltage for a standard I/O pin
when 8 pins are sunk at same time
(see Figure 132 )
Output low level voltage for a high sink I/O pin
when 4 pins are sunk at same time
(see Figure 133 and Figure 136)
V_OH ²⁾
Output high level voltage for an I/O pin
when 4 pins are sourced at same time
(see Figure 134 and Figure 137)

Notes:
1. The I_IO current sunk must always respect the absolute maximum rating specified in Section 12.2.2 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 Section 12.2.2 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.
