** INTERNAL PROCESSOR REGISTER DEFINITIONS
**
** The internal processor register definitions below are annotated
** with one of the following symbols:
**
** 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;
** writes are ignored
