Bits 11:8 – ADDVREGRDY[3:0] Additional Regulator ready x Interrupt. Set to one if additionnal regulator is ready meaning that output voltage is correct.
Set by hardware when the Additional Regulator is ready and the output voltage is correct.
Write one to clear the bit.
Bits 7:5 – BORVDDUSB[2:0] BORVDDUSB Interrupt. Set to one if VDDUSB issue is detected.
Set by hardware when a Brown-Out has been detected on the corresponding VDD_USB.
Write one to clear the corresponding bit.
Bit 4 – BORVDDIOB BORVDDIOB Interrupt. Set to one if VDDIOB issue is detected.
Set by hardware when a Brown-Out has been detected for VDDIOB.
Write one to clear the corresponding bit.
Bit 3 – ULDOOVHEAT User LDO Regulator OverHeat Interrupt. Is set to one if overheat condition is detected.
Set by hardware when the User LDO overheat condition is detected.
Write one to clear the corresponding bit.
Bit 2 – ULDORDY User LDO Regulator Ready Interrupt. Set to one if ULDO is ready meaning that output voltage is correct.
Set by hardware when the User LDO is ready to operate.
Write one to clear the corresponding bit.
Bit 1 – LVDRDY Low Voltage Detector Ready Interrupt. Set to one if LVD is ready to operate.
Set by hardware the Low Voltage Detector is ready to operate.
Write one to clear the corresponding bit.
Bit 0 – LVDET Low Voltage Detector Interrupt. Set to one if VDDIO crosses the treshold voltage in the good direction according to LVD.DIR.
Set by hardware if VDDIO crosses the threshold voltage in a “good” direction according to LVD.DIR.
Write one to clear the corresponding bit.
