Shadow Register Problem

[The Lucas]

Do you consider macros more or less readable than what you have?

A macro for that statement off the top of my heads is

#define writeShadow(S,R)   while((S).CANMC.bit.CCR==0){(S).CANMC.all=(R).CANMC.all;};

Then you just say:

writeShadow(ECanaShadow,ECanaRegs)

I haven't tested that, but it should be close. I assume those are the structs that are going to change from statement to statement. Anyway it is a start if you like it.
