already jumps over some portion of data already, so this option basically
just increases the size of this region (and the resulting binary).

(Push-pull output), the pin is connected to the collector (for a NPN
transistor) or the drain (for a MOSFET) of a transistor, respectively.
The pin then either forms an open circuit or a connection to ground,
depending on the state of the transistor.
