NOTE: In the S3C8275X/C8278X/C8274X microcontroller,
pages 0-2 are implemented.
Pages 0-2 contain all of the addressable
registers in the internal register file.
Each register pointer (RP) can independently point
to one of the 24 8-byte "slices" of the register file
(other than set 2). After a reset, RP0 points to
locations C0H-C7H and RP1 to locations C8H-CFH
(that is, to the common working register area).
