PRODUCTION DATA
An SPI bus is used to set device configurations, operating parameters, and read out diagnostic information on the DRV871x-Q1 devices. The SPI operates in slave mode and connects to a master controller. The SPI input data (SDI) word consists of a 16 bit word, with an 8 bit command and 8 bits of data. The SPI output data (SDO) word consists of the fault status indication bits and then the register data being accessed for read commands or null for write commands. The data sequence between the MCU and the SPI slave driver is shown in Figure 8-30.
A valid frame must meet the following conditions:
