The SVSMH supervises and monitors the VCC. SVSMH has a programmable threshold setting and can be used by the application to generate a reset or an interrupt if the VCC dips below the desired threshold. In supervisor mode, the SVSMH generates a device reset (POR class reset). In monitor mode, the SVSMH generates an interrupt. The SVSMH can also be disabled if monitoring and supervision of the supply voltage are not required (offers more power savings).
