I'm just starting to learn about MCUs and am reviewing the datasheet for the STM8S003F3. In the pin description table, I came across some symbols that I'm not quite sure about, such as bold X with underline (X), regular X (X), and dash (-). What do these symbols mean?

    dash is not available or not applicable.

    X is supported.

    bold X with underline is the pin state after reset

      A quick heads up:

      Other mfgrs retain pin->function assignments.

      ST Ports will still be ports, but "other" functions DO change with the package.

      I got the "wake up" on an STM8S003 TSSOP-20 VS QFP-32.

      If you're going to proto in a different package, keep it in mind.  <<<)))
