Offloading bitbanging from the main processor (NRF9160)

[RayCali]

Hi!

In my project i am using a motion sensor that uses a custom protocol. This has resulted in needing to implement bitbanging for it to work. The issue with this is that it takes resources from the main processor and halts other tasks that need to be done (due to the thread being occupied). I tried to see if the nrf9160 had any Programmable Real-Time Units (PRUs) but could not find any. My question is if there is any other way to offload the bitbanging from the main processor. Any tips are appreciated!
