8.3.1.2.1 Serial Peripheral Interface (SPI)

The SPI devices support a serial communication bus that lets an external controller send and receive data with the DRV8343-Q1 device. This support lets the external controller configure device settings and read detailed fault information. The interface is a four wire interface using the SCLK, SDI, SDO, and nSCS pins which are described as follows:

• The SCLK pin is an input that accepts a clock signal to determine when data is captured and propagated on the SDI and SDO pins.
• The SDI pin is the data input.
• The SDO pin is the data output. The SDO pin has a push-pull output structure.
• The nSCS pin is the chip select input. A logic low signal on this pin enables SPI communication with the DRV8343-Q1 device.
