Thanks a lot for your help!

BTW, I found in the latest Renesas SH proprietary compiler, there is already an option to change the default bit-field allocation so that bit-field's members are allocated from the lower bit, which is same as GCC.


It seems fundamental to me that bit fields must be allocated in a
manner consistent with the processor addressing, or you can get
non-contiguous fields.
