Section 8 Bus State Controller (BSC)
Area 5: Area 5 is an area with address bits A26–A24 set to 101 and an address range of
H'5000000–H'5FFFFFF and H'D000000–H'DFFFFFF. Figure 8.8 shows a memory map of area 5.
Area 5 is allocated to on-chip supporting module space when the A27 address bit is 0 and external
memory space when A27 is 1. In on-chip supporting module space, bits A23–A9 are ignored and
the shadows are in 512-byte units. The bus width is 8 bits when the A8 bit is 0 and 16 bits when
A8 is 1. When on-chip supporting module space is accessed, the CS5 signal is not valid. In
external memory space, the A23 and A22 bits are not output and the shadow is in 4-Mbyte units.
The bus width is always 16 bits. When external memory space is accessed, the CS5 signal is valid.

Note: * Some on-chip supporting module registers can only be accessed as 8-bit registers even
Logical address
though they occupy 16 bits (see Appendix A).
