Memory Space Expansion Features
Memory Space Expansion Features
Table 1.7.1. The way of setting memory space expansion mode and corresponding memory space
Here follows the description of the memory space expansion features.
With the processor running in memory expansion mode or in microprocessor mode, the memory space
expansion features provide the means of expanding the accessible space. The memory space expansion
features run in one of the three modes given below.
Use bits 5 and 4 (PM15, PM14) of processor mode register 1 to select a desired mode. The external
memory area the chip select signal indicates is different in mode so that the accessible memory space
varies. Table 1.7.1 shows how to set individual modes and corresponding accessible memory spaces. For
external memory area the chip select signal indicates, see Table 1.10.1 on page 31.
Normal mode (no expansion)
Expansion mode
Here follows the description of individual modes.
(1) Normal mode (a mode with memory not expanded)
‘Normal mode’ means a mode in which memory is not expanded.
Figure 1.7.1 shows the memory maps and the chip select areas in normal mode.
(1) Normal mode (no expansion)
(2) Memory space expansion mode (to be referred as expansion mode)
Note 1: These memory maps show an instance in which PM13 is set to 0; but in the case of products in which the internal
Note 2: The memory maps in single-chip mode are omitted.

Normal mode (memory area = 1M bytes for PM15 = 0, PM14 = 0)
RAM and the internal ROM are expanded to over 15 Kbytes and 192 Kbytes, respectively, they show an instance
in which PM13 is set to 1.
