Bit Bit description

[7:3] Reserved

[2] DSFT_DIS: drain-source fault disable.

This bit can be written only when the DISABLE bit (in status register 1) is "1", otherwise the write

operation to this bit is ignored. Note: this bit is not set to default in case of fail-safe errors.

0: a drain-source monitoring error causes the turn-off of the affected driver (functional error

reported)

1: a drain-source monitoring error does not cause the turn-off of the affected driver (global

warning reported)

0: ISTEST disabled

1: ISTEST enabled

[0] OCFT_DIS: overcurrent filter time disable (for RPD)

0: overcurrent filter time enabled

1: overcurrent filter time disabled
