S3C831B/P831B

PROGRAM MEMORY (ROM)

Program memory (ROM) stores program codes or table data. The S3C831B has 64K bytes internal mask-

programmable program memory.

The first 256 bytes of the ROM (0H–0FFH) are reserved for interrupt vector addresses. Unused locations in this

address range can be used as normal program memory. If you use the vector address area to store a program

code, be careful not to overwrite the vector addresses stored in these locations.

The ROM address at which a program execution starts after a reset is 0100H.
