Address Map

Figure 9.2 shows the address format used by this LSI.

Output address:

Output from the address pins

CS space selection:

Decoded, outputs

CS0 when A31 to A24 = 00000000

Space selection:

Not output externally; used to select the type of space

On-chip ROM space or CS0 space when 00000000 (H'00)

Reserved (do not access) when 00000001 to 11111110 (H'01 to H'FE)

On-chip peripheral module space or on-chip RAM space when 11111111 (H'FF)

A31 to A24

A23, A22

A21 to A18

A17

Figure 9.2 Address Format

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) for the corresponding

areas when bits A31 to A24 are 00000000.

• A17 to A0 are output externally. A21 to A18 are not output externally.

Table 9.2 shows the address map.
