According to the LQFP package drawing 98ASA00452D, there is an exposed copper pad underneath the package. Described as exposed flag in the package drawing document.
I can't find any reference to this pad in the F-series datasheet.
Or the f series reference manual.
I have only found references to pins 1-176.
Have I missed something in the manual?
What is the exposed pad connected to? I'm assuming ground.
