External BusesMitsubishi microcomputersM16C / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTER(2)2-Mbyte ROM and 256-Kbyte SRAM Connection ExampleFigure 5.3.8 shows how to connect 2-Mbyte ROM and 256-Kbyte SRAM in microprocessor mode. Locateboth the 2-Mbyte ROM and 256-Kbyte SRAM in the CS0 area that has been extended in memory spaceextension mode 2.Specifically, locate the 2-Mbyte ROM in the area comprised of banks 4 though 7 and the 256-KbyteSRAM in the area of bank 0.CNVss CS0CS1BYTE CS2CS3A0 to A19CS0CS3A16toA0RDWRA1toA0S1S2OEWDQ1toDQ8D0toD7CS3CS0CS2CS1A19A17 to A0RDA20A19A18A17 to A0CEOEDQ0toDQ7D0toD7256K bytes SRAM2M bytes ROMRDWRD0 to D7M16C/62Figure 5.3.8. 2-Mbyte ROM and 256-Kbyte SRAM Connection Example_______ _______ _______Enter the signal decoded from outputs CS0 and CS3 to the 2-Mbyte ROM’s chip enable pin.
