3.4 Internal RAM Area and SFR Area
The 8 Mbyte area at addresses H'0080 0000 to H'00FF FFFF in the user space accommodates the
internal RAM area and Special Function Register (SFR) area. Of this, a 128 Kbytes of address
space from H'0080 0000 to H'0081 FFFF is the area that the user can actually use. All other areas
here comprise a ghost area in units of 128 Kbytes. (When programming, do not use this ghost area
intentionally.)
