Certus-NX: What is the Maximum Current per bank?

Description:
The maximum 64 mA per bank (8 IO with 8 mA) applies when selecting # of IO switching simultaneously. If desired is to use 16 mA with 8 IO switching, the overall junction temperature will be 2X higher. The source and sink current will depend on load conditions so to manage the electromigration due to thermal, users must calculate (using the power calculator) the worst-case junction temperature for a given use case and make sure that Tj must be < 125 \u00B0C (for a given ambient temp) in Simultaneous Switching Output (SSO) environment.
Similarly, to restate, The "Data Sheet Pin Summary tables" defined in the document is the pinout file of the stated device. This can be generated through Radiant tool by opening the Device Constraint Editor then Select File > Export > Pinout file > Save the file to your desired location. This shows the IO groupings of each Bank.
