INTERRUPT STRUCTURE S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X
5-4
INTERRUPT VECTOR ADDRESSES
All interrupt vector addresses for the S3C8275X/C8278X/C8274X interrupt structure are stored in the vector
address area of the internal 16-Kbyte ROM, 0H−3FFFH, or 8, 4-Kbyte (see Figure 5-3).
You can allocate unused locations in the vector address area as normal program memory. If you do so, please be
careful not to overwrite any of the stored vector addresses (Table 5-1 lists all vector addresses).
The program reset address in the ROM is 0100H.
The reset address of ROM can be changed by a smart option only in the S3F8275X (Full-Flash Device). Refer to
the chapter 16. Embedded Flash Memory Interface for more detail contents.
