Register Grouping的问题

蓝色永恒

最近在ACPI 中看到一句：
$ [  J5 I- M, v/ SThe fixed-position bits within a register grouping can be split between the two register blocks. This allows the bits within a register grouping to be split between two chips.
不知何解，想不出来，请各位大侠多多指教，多谢~

Look around 'Figure 4-5 Example Fixed Hardware Feature Register Grouping' in ACPI spec 3.0b
