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.
Hi,
Could you please send the previous packet just before this packet or was this the first SPI data packet written to the device? Was this send immediately after power on or waking up from sleep using nSLEEP 0 to 1 transition? In both the cases did you wait for a power on or wake up delay time before starting the SPI communication? This delay should be about 1 ms. Please see below. Thanks.
