- `DIR/SIDE1` is the step direction pin. During reads or writes, `SIDE1` is
also multiplexed onto it, because some drives expect this. This is harmless
on other drives because the `DIR` pin is ignored during reads or writes.
- `TX` is the debug UART port. It's on pin 12.7 because the board routes it
to the USB serial port on the programmer, so you can get debug information

**Important SCP note:** import (`fluxengine convert scptoflux`) should be

done with great caution as FluxEngine files contain features which can't be
