PRODUCTION DATA.
SPI bus is used to set device configurations, operating parameters, and read out diagnostic information on the DRV89xx-Q1 device. 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 8-bit register data and the first 8 bits make up the Status Register with Fault Status indication. The data sequence between the MCU and the SPI slave driver is shown in Figure 69.
A valid frame must meet the following conditions:
