• tx_mask — bitmask representing active TX slots. examples are exact: 0xf for normal 4 channel TDM, and 0xf0 for shifted 4 channel TDM. periodt. 💅
• rx_mask — not used. the original says "no used" and honestly same, bestie — just ignore it. 🙈
• slots — number of slots in use. 🔢
• slot_width — width in bits for each slot. 🎀
