🔥 DESCRIPTION 🔥

So this function needs to be called with a lock held, fr fr. That is not a lil suggestion, bestie — it is the requirement. 😭 The reason is that it needs two i2c write byte operations, because these registers (0x27 0x28) don't work in word mode accessing. periodt. 💅

Lock held. Two i2c write byte operations. Registers 0x27 0x28. No word mode accessing. That is the whole assignment. 🎀
