Hello, I have something need to ensure: when the mcu send a wrong address or not a 16 or 24 bit data, will it send the data back to the mcu?
the datasheet said that TJA1128 will not execute write operation it but I need to know whether it will send the wrong data back to the mcu, since i meet a problem that when I send anything to the TJA1128 ,it will send what I send back.
the chip I use is
CY8C4146LQS-S433/QFN-40(an PSOC chip), I think the way I send the data is ok:
thank you

You can see the SPI write operation pattern, SPI is fullduplex data transfer, when write data0 in SDI the same data appears in SDO.
