IMXRT1062 Hardfault Reading CAN3 ERFCR Register

According to the 1060RM setting the ERFCR will enable the Enhanced FIFO.  However when I try to even read the register in the FLEXCAN  example it throws a hard fault.  When I tried it in my own application on a imxrt1062 I also get a hard fault at that register address.  Needless to say I can't set it either.

 

So the question is, what is the cause of the issue and is Enhanced FIFO even enabled and the RM is incorrect?
