This section describes the Voltage and Thermal Manager (VTM) module in the device.
VTM provides the control, status as well as interrupt and event generation related to integrated temperature sensors and thermal events programed by the user. VTM also contains a set of memory mapped registers that store device-specific operating voltages (AVSVNOM) set during device testing. These values may be used for the system AVS software to adjust operating voltages for the device to achieve optimal operating power.
The device supports one VTM module - WKUP_VTM0. Table 5-1331 shows VTM module allocation within device domains.
