Area 7: Area 7 is the area where addresses A26–A24 are 111 and its address range is H'7000000–
H'7FFFFFF and H'F000000–H'FFFFFFF. Figure 8.10 is 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 an bus width of 32 bits. The on-chip RAM capacity is 1 kbytes, so
A23–A10 are ignored and the shadows are in 8-kbyte units. During on-chip RAM access, the CS7
signal is not valid.
