INTERRUPT STRUCTURE
S3C80M4/F80M4
INTERRUPT VECTOR ADDRESSES
All interrupt vector addresses for the S3C80M4/F80M4 interrupt structure are stored in the vector address area of
the internal 4-Kbyte ROM, 0H–FFFH (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.
