The BGM_CUTOFF[1:0] bits set the debounce time before the DMS sends a critical fault notification and

disables the power stages of the voltage regulators.

14.12.2.3 VDIG_OV monitor fault protection

When the DMS detects a fault condition on the VDIG_OV monitor, the DMS will assert the FS0B output and the

VDIG_OV_I interrupt will be set. If the VDIG_OV fault condition is temporary, no critical fault will be generated,

but the VDIG_OV_I flag and the FS0B output remain asserted until the MCU is able to clear the VDIG_OV flag

and release the FS0B.

If the VDIG OV fault condition is persistent, the OTP_VDIGOV_RSTB[1:0] bits set the debounce time before the

DMS sends a critical fault to assert the RSTB pin.
