3.3 Internal ROM and External Extended Areas
The 8-Mbyte area in user space addresses from H'0000 0000 to H'007F FFFF is used for the
internal ROM and external extended areas.
For details on how the locations of the internal ROM and external extended areas vary depending
on 32172/32173 operation mode settings, refer to Section 3.2, "Operation Modes."
3.3.1 Internal ROM Area
The internal ROM is allocated to the addresses listed below. Located at the beginning of this area
is the EIT vector entry (and ICU vector table).

H'0000 0000-H'0003 FFFF
3.3.2 External Extended Area
The external extended area is available only when external extended or processor mode is
selected for the chip operation mode. For access to the external extended area, the 32172/32173
outputs the control signals that are required for accessing an external device.
___ ___ ___
___
The 32172/32173's CS0, CS1, CS2, and CS3 signals are output according to the address into
___
which the external extended area is mapped. Namely, the CS0 signal is output for the CS0 area,
___
___
___
the CS1 signal is output for the CS1 area, the CS2 sognal is output for the CS2 area, and the CS3
signal is output for the CS3 area.
