5.2.2 Chip Selects and Address Bus
Chip selects (P4
memory space into four. To use the chip select, the chip select output must be enabled by setting the
chip select control register. Figure 5.2.2 shows addresses in which chip selects become active (“L”).
Since the extent of the internal area and the external area in memory expansion mode is different from
those in microprocessor mode, there is a difference between areas for which CS0 is output. When an
internal ROM/RAM area is being accessed, no chip select is output, and the address bus does not
change (the address of the external area that was accessed previously is held).
