NOTE:
In the S3C84E5/C84E9/P84E9 microcontroller,
pages 0-1 are implemented. Pages 0-1
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).
