32180 Group User’s Manual (Rev.1.0)
3.3 Internal ROM and Extended External Areas
The 8-Mbyte area in the user space from the address H’0000 0000 to the address H’007F FFFF comprise the
internal ROM and extended external areas. For the address mapping of these areas that differs with each opera-
tion mode, see Section 3.2, “Operation Modes.”
3.3.1 Internal ROM Area
The internal ROM is allocated to the addresses shown below. Located at the beginning of this area is the EIT
vector entry (and the ICU vector table).

H’0000 0000 to H’000F FFFF
3.3.2 Extended External Area
The extended external area is only available when external extension or processor mode is selected by opera-
tion mode settings. When accessing the extended external area, the control signals necessary to access exter-
nal devices are output.
The CS0# through CS3# signals are output corresponding to the address mapping of the extended external
area. The CS0#, CS1#, CS2# and CS3# signals are output for the CS0, CS1, CS2 and CS3 areas, respectively.
