Temperature monitoring of each thermistor may be enabled or disabled (register TS_ENABLE) depending on whether the thermistor and its bias circuit is populated on the platform. This enables the thermal monitoring state machine to know if any alert or interrupt associated with the thermistor should be generated. If in register TS_ENABLE the corresponding enable bit is set, the thermistor is connected to the PMIC and the PMIC can poll the sensor. There are three pre-defined and programmable threshold for each of the measurements ALERT0 ALERT1 TCRIT Each ALERT has a 4-bit hysteresis and 4 STATUS bits (A0_ST, A1_ST, CRIT_ST) and for all the ALERT0 a policy register (A0P_EN) is defined in order to allow actions upon crossing thresholds. |
