While we checked the data coming out of Master SPI using a SPI analyzer, we have noticed a strange behavior. For example we are transmitting 7 data say {1,2,3,4,5,6,7}. The master output of SPI data will be {1,1,2,2,3,4,5}. The first 2 data is repeating, but after that it will be as expected. We also checked the regester that holding there data. There is also no repeatation in data. What will be the possible reason for this? Can you help us out.
Hi, have you checked status register for overflow/underflow flags? Data repetitions are typical for that.
Also please clarify used device part number.
