The reversal needs to be done byte-wise. So in this example:

> uint8_t code_lo:4;
The first byte is code_hi and gs, reverse those:
> +#else
> + uint8_t gs:2;
> + uint8_t code_hi:6;
Next byte is update and code_lo, reversed:
> + uint8_t code_lo:4;
> + uint8_t update:4;
> +#endif
I hope that helps :)
