A 32-bit CRC protected SPI interface is used for configuration and control of all

channels and provides status feedback of all diagnostic functions. An active low

reset input, RESN, is used to disable all channels and resets internal registers to

their default values. A safe enable path is provided through the EN_DR pin and the

integrated Fail Safe Pre-driver. An isolated redundant safety switch-off path ensures

that critical internal faults disable the fail safe pre-driver. An active high enable pin,

EN_DR, is used to enable or disable the operation of all channels. When the EN_DR

pin is low, all channels are disabled. A fault output pin is provided and can be used

to generate an external interrupt to the microcontroller whenever a fault is detected.

The user can map specific faults to the FAULTn pin based on their specific system

requirements.
