TSSI is transmitter signal strength indication, which is a close-loop hardware circuit to feedback actual transmitting power as a reference for next transmission. When we setup channel to connect an AP, it does full calibration. When switching bands or channels, it needs to reset hardware status to prevent use wrong feedback of previous transmission. To do TX power compensation reflecting current temperature, it loads tables of compensation values into registers according to channel and band group.
