1.
In the interrupt input column, “eiX” defines the associated external interrupt vector. If the weak pull-up column (wpu) is
merged with the interrupt column (int), then the I/O configuration is pull-up interrupt input, else the configuration is floating
interrupt input.
2.
It is mandatory to connect all available VDD and VDDA pins to the supply voltage and all VSS and VSSA pins to ground.
3.
Pulled-up by hardware when not present on the package.
4.
In the open drain output column, “T” defines a true open drain I/O (P-Buffer and protection diode to VDD are not
implemented).
5.
Internal weak pull-down.
