3.4 Internal RAM and SFR Areas

The 8-Mbyte area from the address H’0080 0000 to the address H’00FF FFFF comprise the internal RAM and

SFR (Special Function Register) areas. Of these, the space that the user can actually use is a 256-Kbyte area

from the address H’0080 0000 to the address H’0083 FFFF. The other areas here are ghosts in 256-Kbyte units.

(Do not use the ghost area intentionally during programming.)

3.4.1 Internal RAM Area

The internal RAM area is allocated to the addresses shown below.
