Thank you!
I understand what you said and I could realize what I want to make.
Best regards,

Yes, I mean that. I understand that "MemoryRegionOps read and write
functions, those work only with byte offsets."
But, I must set a value into a qom register using C bit fields in the guest
source code.
If I use the extract32/deposit32

If you mean the MemoryRegionOps read and write functions, those
work only with byte offsets, because the guest CPU cannot make

Hello,
I would like to access a 4byte-register in 1bit unit.
So, I was supposed to use a bit field to define a register like this.
typedef struct register{
// define register B
uint32_t B1 : 1;
uint32_t B2 : 1;
uint32_t B3 : 30;
}register;
