PROGRAM MEMORY (ROM)

Program memory (ROM) stores program codes or table data. The S3C9484/C9488 has 4K and 8Kbytes of internal

mask programmable program memory. The program memory address range is therefore 0H–0FFFH and 0H-1FFFH.

The S3F9488 have 8Kbytes (locations 0H–1FFFH) of internal multi time programmable (MTP) program memory (see

Figure 2-1).

The first 2-bytes of the ROM (0000H–0001H) are interrupt vector address.

Unused locations (0002H–00FFH except 3CH, 3DH, 3EH, 3FH) can be used as normal program memory.

The location 3CH, 3DH, 3EH, and 3FH is used as smart option ROM cell.

The program reset address in the ROM is 0100H.
