2. CPU and Memory Space
2.1 Overview
2.2 Program Memory Space
This LSI includes 8-bit CPU nX-U8/100 and the memory model is SMALL model.
For details of the CPU nX-U8/100, see “nX-U8/100 Core Instruction Manual”.
The program memory space is used to store program codes, table data (ROM window), or vector tables.
The program codes have a length of 16 bits and are specified by a 16-bit program counter (PC).
The ROM window area data has a length of 8 bits and can be used as table data.
The vector table, which has 16-bit long data, can be used as reset vectors, hardware interrupt vectors, and software
interrupt vectors.
The program memory space consists of one segment and has 16-Kbyte (8-Kword) capacity.
Figure 2-1 shows the configuration of the program memory space.
Note:
・ The 1024 bytes (512 words) from 3C00H to 3FFFH are the test data area.
・ The test data area is rewritable but cannot be used as the program code area.
・ In case Mask ROM version emulation function is not used, write "0FFH" to the test data area. If data in the area is uncertain or
・ In case Mask ROM version emulation function is used, see Chapter 25, "Mask ROM Version Emulation Function" for the write
