    SPI communication - TLF35584 and AURIX TC37x

    Hello,

    I am trying to establish SPI communication with TLF35584 device on my AURIX TC37X MCU. I want to first ensure my read commands to TLF35584 are working before I can continue with the device configuration.

    I am sending a read command to TLF35584 device, however I am not sure if the data coming back from TLF device is good or not. I wish there was a simple device version check which I could have used to verify the read command is ok.

    In my test I am sending Read Command to SBC = 0x4E00 (Read DEVSTAT)
    Response from SBC = 0x81F3
    Cmd = 1
    D7 = DEVSTAT[TRK2EN] = 1
    D6 = DEVSTAT[TRK1EN] = 1
    D5 = DEVSTAT[COMEN] = 1
    D4 = DEVSTAT[STBYEN] = 1
    D3 = DEVSTAT[VREFEN] = 1
    D2-DO = DEVSTAT[STATE] = 01
    Parity = 1

    Does this data makes sense ? Is my communication ok ?

    The value seems be valid (voltages enabled and state is INIT_STATE).
