**
**	RW - The register may be read and written
**	RO - The register may only be read
**	WO - The register may only be written
**
**  For RO and WO registers, all bits and fields within the register are
**  also read-only or write-only.  For RW registers, each bit or field
**  within the register is annotated with one of the following:
**
**	RW  - The bit/field may be read and written
** 	RO  - The bit/field may be read; writes are ignored
**	WO  - The bit/field may be written; reads return UNPREDICTABLE
**	WZ  - The bit/field may be written; reads return a zero value
**	W0C - The bit/field may be read; write-zero-to-clear
**	W1C - The bit/field may be read; write-one-to-clear
**	WA  - The bit/field may be read; write-anything-to-clear
**	RC  - The bit/field may be read, causing state to clear;
