**MBX1 send to MBX17. The program constantly transmits data back to back and checks the correctness of the data. * * * *
The /*eCAN control register requires 32 bit access. If you want to write to a single bit, the compiler might make it into 16 bit access. One solution here is to force a 32 bit access with the shadow register. Reads the entire register into a shadow register. This visit will be in 32 place. With a 32 bit write operation needs to change, then the value is copied back to the eCAN register.
