### RP2040 PIO implementation
If you're using RP2040 based board and want to use other pins that the one with hardware support of RX/TX, you can try
using PIO implementation of two-way wire protocol. Typical use cases for it are premade boards, made with QMK's
bitbanging protocols in mind.
In order to enable it, you must:
- install Circuit Python in 7.2+ version
- add `adafruit_pioasm.mpy` library to lib or root folder of a board
- pass `use_pio=True` into `Split()` constructor
