Part Number: TCAN4550

Hi Team,

Can user change SPI mode on TCAN4550? Datasheet states that TCAN4550 sample input data on CLK rising edge, while my customer's DSP is set to falling edge sampling, will this casue issue? 

Regards,

    Charles,

    The SPI sampling edge cannot be changed on the TCAN4550-Q1, and with the DSP having a different sampling edge, this will likely cause timing issues. Is there a way to change the sampling edge on the DSP? Usually this can be configured in most controllers.

    Regards,
