Thank you in advance!

I have the questions as below:

1. Does mpc8039 flexcan support loopback mode?

    During debug, I found that I can soft reset the flexcan successfully, but when I try to send messages out through MB in the loopback mode, it failed. I found the code field in the MB always as the value I wrote into it, 0xC, it is never changed.

2.  If I set the flexcan in normal mode, I will can not access the flexcan regsiter address space, I should set the mode as

     supervisor mode, then I can access flexcan address space, but still can not access "RX Individual Mask Registers",

    Why?
