PROGRAM MEMORY (ROM)
Program memory (ROM) stores program code or table data. The S3C9228 has 8K bytes of mask-programable
program memory. The program memory address range is therefore 0H-1FFFH. The first 2 bytes of the ROM
(0000H–0001H) are an interrupt vector address. The program reset address in the ROM is 0100H.
