Section 8 Bus State Controller (BSC)
Area 7: Area 7 is an area with address bits A26–A24 set to 111 and an address range of
H'7000000–H'7FFFFFF and H'F000000–H'FFFFFFF. Figure 8.10 shows a memory map of area 7.
Area 7 is allocated to external memory space when A27 is 0 and on-chip RAM space when A27 is
1. In external memory space, the bus width is 8 bits. The A23 and A22 bits are not output and the
shadow is in 4-Mbyte units. When external memory is accessed, the CS7 signal is valid.
The on-chip RAM space has a bus width of 32 bits. In the SH7032, the on-chip RAM capacity is 8
kbytes, so A23–A13 are ignored and the shadows are in 8-kbyte units. In the SH7034, the on-chip
RAM capacity is 4 kbytes, so A23–A12 are ignored and the shadows are in 4-kbyte units. During
on-chip RAM access, the CS7 signal is not valid.
