This register is used to enable ECC on the CAN1 RAM. ECC errors can be injected into the write path using bits in this register. This register contains interrupt status of the ECC single/double bit error.
Only reset by a cold reset (ignores warm reset).

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
