-**
-** 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

-** 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;

-//
-// 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 an UNPREDICTABLE result
-// WZ - The bit/field may be written; reads return a 0
-// WC - The bit/field may be read; writes cause state to clear
-// RC - The bit/field may be read, which also causes state to clear;
-// writes are ignored

-** Macros for saving/restoring data to/from the PAL impure scratch
-** area.
-**
-** The console save state area is larger than the addressibility
-** of the HW_LD/ST instructions (10-bit signed byte displacement),
-** so some adjustments to the base offsets, as well as the offsets
-** within each base region, are necessary.
-**
-** The console save state area is divided into two segments; the
-** CPU-specific segment and the platform-specific segment. The
-** state that is saved in the CPU-specific segment includes GPRs,
-** FPRs, IPRs, halt code, MCHK flag, etc. All other state is saved
-** in the platform-specific segment.
-**
-** The impure pointer will need to be adjusted by a different offset
-** value for each region within a given segment. The SAVE and RESTORE
-** macros will auto-magically adjust the offsets accordingly.
