− Since test program data is stored in the 1024Byte (512Word) test data area (0:0FC00H to 0:0FFFFH) of Segment 0,
− The address “0: 0FC00H to 0: 0FDFFH” in the test area is write-able and erase-able. Fill the area with “0FFH”. If
− The area 0:E000H to 0:FDFFH of Segment 0 cannot be used as a ROM window area.
− Set “0FFH” data (BRK instruction) in the unused area of the 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 1 segments and has 64-Kbyte (32-Kword) capacity.
Figure 2-1 shows the configuration of the program memory space.
Notes:
this area cannot be used as a program code area.
data in the area is uncertain or other data (i.e. not 0FFH), operating with the code can not be guranteed.
