Hardware interface devices convert the four SPI pins into four resistor configurable inputs, GAIN, IDRIVE, MODE, and VDS. This allows for the application designer to configure the most commonly used device settings by tying the pin logic high or logic low, or with a simple pullup or pulldown resistor. This removes the requirement for an SPI bus from the external controller. General fault information can still be obtained through the nFAULT pin.
For more information on the hardware interface, see the Pin Diagrams section.
