A thermal domains can be the MCU or the AP. Each thermal domains contain up to seven controllers, each thermal controller handle up to four thermal sensors. The LVTS has two Finite State Machines (FSM), one to handle the functionin temperatures range like hot or cold temperature and another one to handle monitoring trip point. The FSM notifies via interrupts when a trip point is crossed. The interrupt is managed at the thermal controller level, so when an interrupt occurs, the driver has to find out which sensor triggered such an interrupt. The sampling of the thermal can be filtered or immediate. For the former, the LVTS measures several points and applies a low pass filter.
