The document "PG096 (v5.1) May 16, 2023 CAN v5.1" [1] lists the XCAN_ECC_CFG_OFFSET as reserved, although it has a section "ECC Configuration Register". [1] https://docs.xilinx.com/viewer/book-attachment/Bv6XZP9HRonCGi58fl10dw/ch1ZLpOt4UKWNub7DXjJ7Q The other registers (XCAN_TXTLFIFO_ECC_OFFSET, XCAN_TXOLFIFO_ECC_OFFSET, XCAN_TXOLFIFO_ECC_OFFSET) are also listed as reserved and not even mentioned on the document.
