Figure 1.10.2. Memory location and chip select area in each processor mode
Figure 1.10.2 shows the memory maps and the chip selection areas effected by PM13 (the internal re-
served area expansion bit) in each processor mode for the product having an internal RAM of more than
15K bytes and a ROM of more than 192K bytes.
