部件号: DRV8899-Q1
Recently in the use of 8899 this chip, and then ran into a problem, that is, in read FAULT Status Register, 8899 will restore the SPI_ERROR this fault, I'm not too clear about what is caused by this, the following figure oscilloscope pink that is, line 4 is the 8899 issued by the line. I'm not sure what causes this, the pink line in the oscilloscope below is from the 8899. Please give me an answer, thank you.
