29.7.3 Interrupt Flag Status and Clear

Note: Subsequent to an interrupt flag being cleared, the flag must be read back to verify the clear before exiting the ISR. Failure to do this can result in duplicate interrupts.

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 threshold 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.
