Does the TCAN4550 offer any buffering of messages, either FIFO or mailboxes? Does it buffer TX messages? 

Thank you!

    Hi Lenio,

    Yes, the device has 2k of RAM located in registers 0x8000 through 0x87FF that can be assigned as either buffers (priority-based) or FIFOs (timing-based) for transmitting and receiving CAN frames. The memory space is configured via registers 0x10A0 (RXF0C), 0x10AC (RXBC), 0x10B0 (RXF1C), 0x10BC (RXESC), 0x10C0 (TXBC), 0x10C8 (TXESC), and 0x10F0 (TXEFC).

    Regards,
    Max
