21  * Global Utility Registers.

23  * Not all registers defined in this structure are available on all chips, so
24  * you are expected to know whether a given register actually exists on your
25  * chip before you access it.
26  *
27  * Also, some registers are similar on different chips but have slightly
28  * different names.  In these cases, one name is chosen to avoid extraneous
29  * #ifdefs.
