1. In the interrupt input column, “eiX” defines the associated external interrupt vector. If the weak pull-up column (wpu) is
2. It is mandatory to connect all available V
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 V
5. Internal weak pull-down.
