Address Space 3.2 External Address Space The external address space is divided into four CS areas (CS0 to CS3), each corresponding to the CSn# signal output from a CSn# (n = 0 to 3) pin. Figure 3.2 shows the address ranges corresponding to the individual CS areas (CS0 to CS3) in on-chip ROM disabled extended mode. Figure 3.2 Correspondence between External Address Spaces and CS Areas (In On-Chip ROM Disabled Extended Mode) Reserved area*1 Reserved area*1 Reserved area*1 Reserved area*1 0500 0000h 06E0 0000h 07E0 0000h 06DF FFFFh 07DF FFFFh 07FF FFFFh CS3 (2 Mbytes) FFFF FFFFh FF00 0000h CS0 (2 Mbytes) 05DF FFFFh 05E0 0000h 0600 0000h 05FF FFFFh CS2 (2 Mbytes) CS1 (2 Mbytes) 0700 0000h 06FF FFFFh FFE0 0000h FFDF 0000h Reserved area*1 External address space (CS area) Reserved area*1 External address space (CS area)*2 0000 0000h 0008 0000h FFFF FFFFh On-chip ROM disabled extended mode 0010 0000h 0100 0000h 0800 0000h FF00 0000h 00FF C000h ECCRAM 000A 4000h 000A 6000h Reserved area*1 0002 0000h 0500 0000h On-chip RAM Peripheral I/O register Peripheral I/O register Reserved area*1 Reserved area*1 Note 1. Reserved areas should not be accessed. Note 2. The CS0 area is disabled in on-chip ROM enabled extended mode. In this mode, the memory map for the addresses above 0800 0000h is as shown in Figure 3.1. |
