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.
