Figure 9.6
Figure 9.6 shows the External Memory Connect Example in 4-Mbyte Mode.
In this example, the CS pin of 4-Mbyte ROM is connected to the CS0 pin of microcomputer. The 4 Mbyte ROM
address input AD21, AD20 and AD19 pins are connected to the CS3, CS2 and CS1 pins of microcomputer,
respectively. The address input AD18 pin is connected to the A19 pin of microcomputer. Figures Figure 9.7 to 9.9
show the Relationship of Addresses Between the 4-Mbyte ROM and the Microcomputer for the Case of a
Connection Example in Figure 9.6.
In microprocessor mode, or in memory expansion mode where the PM13 bit in the PM1 register is “0”, banks are
located every 512 Kbytes. Setting the OFS bit in the DBR register to “1” (offset) allows the accessed address to be
offset by 40000h, so that even the data overlapping a bank boundary can be accessed in succession.
In memory expansion mode where the PM13 bit is “1,” each 512-Kbyte bank can be accessed in 256 Kbyte units
by switching them over with the OFS bit.
Because the SRAM can be accessed on condition that the chip select signals S2 = H and S1 =L, CS0 and CS2 can
be connected to S2 and S1, respectively. If the SRAM does not have the input pins to accept “H” active and “L”
active chip select signals(S1, S2), CS0 and CS2 should be decoded external to the chip.
