Figure 9.2 shows the address format used by this LSI.
This chip uses 32-bit addresses:
• Bits A31 to A24 are used to select the type of space and are not output externally.
• Bits A23 and A22 are decoded and output as chip select signals (CS0 to CS7) for the
• Bits A21 to A0 are output externally.
Table 9.2 shows the address map.
corresponding areas when bits A31 to A24 are 00000000 or 00000001.

A31 to A24
Space selection:
Not output externally; used to select the type of space
On-chip ROM space or CS space when 00000000 or 00000001 (H'00 or H'01)
Reserved (do not access) when 00000010 to 11111110 (H'02 to H'FE)
On-chip peripheral module space or on-chip RAM space when 11111111 (H'FF)
A23, A22
CS space selection:
Decoded, outputs CS0 to CS7 when A31 to A24 = 00000000 or 00000001
