S3C84E5/C84E9/P84E9 INTERRUPT STRUCTURE
5-5
INTERRUPT VECTOR ADDRESSES
All interrupt vector addresses for the S3C84E5/C84E9/P84E9 interrupt structure are stored in the vector address area
of the internal 16/32-Kbyte ROM, 0H–3FFFH/0H–7FFFH (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.
