PRELIMINARY DATA26 SH-5 physical address map2.6 SH-5 physical address mapEach memory block is associated with a particular p-port and hence with aparticular module. The mapping from memory blocks to p-ports is notprogrammable on SH-5. The mapping defines the SH-5 physical address map and isgiven in Table 4.P-portacronym(or RESERVED)BlocktypeDestinationrangePhysical address rangeD R A FTPhysicaladdressspaceFEMI_db DB 0x00 to 0x07 0x00000000 to 0x07FFFFFF 128 MbyteFEMI_cb CB 0x08 0x08000000 to 0x08FFFFFF 16 MbytePERIPHERAL_cb CB 0x09 to 0x0A 0x09000000 to 0x0AFFFFFF 32 MbyteDebug_link DB 0x0B 0x0B000000 to 0x0BFFFFFF 16 MbyteDebug_cb CB 0x0C 0x0C000000 to 0x0CFFFFFF 16 MbyteCPU CB 0x0D 0x0D000000 to 0x0DFFFFFF 16 MbyteDMAC CB 0x0E 0x0E000000 to 0x0EFFFFFF 16 MbyteRESERVED UB 0x0F to 0x3F 0x0F000000 to 0x3FFFFFFF 784 MbytePCI_db DB 0x40-0x5F 0x40000000 to 0x5FFFFFFF 512 MbytePCI_cb CB 0x60 0x60000000 to 0x60FFFFFF 16 MbyteRESERVED UB 0x61 to 0x6F 0x61000000 to 0x6FFFFFFF 240 MbyteSHwy Socket UB 0x70 to 0x7F 0x70000000 to 0x7FFFFFFF 256 MbyteEMI_DRAM DB 0x80 to 0xFE 0x80000000 to 0xFEFFFFFF 2032 MbyteEMI_cb CB 0xFF 0xFF000000 to 0xFFFFFFFF 16 MbyteTable 4: SH-5 physical address mapThe physical address map is organized so that each p-port deals with a contiguousrange of blocks and with a set of blocks of the same type. The only exception to thisorganization is the treatment of accesses to undefined blocks. All accesses toundefined blocks are routed to the Debug_cb p-port where they are handled aserrors.SuperH, Inc.SH-5 System Architecture, Volume 1: System 05-SA-10001 v1.0
