A 24-bit serial peripheral interface (SPI) is used for configuring and controlling the eight half-bridges or four H‑bridge. SPI status registers provide high-level diagnostic information such as supply voltage monitoring, the charge pump voltage monitoring, temperature warning and overtemperature shutdown.
