I have ran into a problem that someone here might be able to answer. The problem is that I am programing a microcontroller using bit fields created in a structure. The problem comes as I am trying to modify a series of registers that only have 32-bit access. I can't read or write to these registers using a conventional bit field because otherwise the registers would be corrupted. The solution I have read makes perfect sense. You create another structure and then load up the entire 32-bit of the same register and then modify and read the bit fields from that shadow register. Unfortunately, this makes the code a lot more convoluted in in that you constantly have to be making sure that both structures are being updated as seen in the following example I have below which is only checking the a flag. Any solutions on how to make this code more readable or is this the best way to program those registers?
Edit: I know I can just write to those registers in one go but that is a step backwards in readability from where I am right now.

 while(ECanaShadow.CANMC.bit.CCR==0){ECanaShadow.CANMC.all=ECanaRegs.CANMC.all;};
}
