The PMM includes an integrated voltage regulator that supplies the core voltage to the device . The PMM also includes the supply voltage supervisor (SVS) and brownout protection. The brownout circuit is implemented to provide the proper internal reset signal to the device during power on and power off. The SVS circuitry detects if the supply voltage drops below a safe level. SVS circuitry is available on the primary and core supplies.
