8.1.5 Address Format
Figure 8.2 shows the address format used in the SH7065.
A31 A30–A26 A25
A0
Output address: Output from address pins
CS space selection: Decoded, outputs CS0 to CS5
Space selection: Not output externally; used for space type selection
0: CS space
1: XRAM/YRAM space, on-chip peripheral module space
Figure 8.2 Address Format
The SH7065 uses 32-bit addresses.
Bit A31 is used to select the type of space. This signal is not output externally.
Bits A30 to A26 are decoded to provide the chip select signal (CS0 to CS5) for the area, which is
output.
Bits A25 to A0 are output externally.
Table 8.3 shows the address maps when the maximum range is set for each space.
