Vector Table for MC9S08AC128

Hi,

 

I have a vector table for MCS9S08AC128 which has been hardcoded from ff9c but each vector is taking three bytes instead of 2 bytes as per the data sheet .I commented all the vector constants

 

Snippet from .map file

.abs_section_ff9c 3 R 0xFF9C 0xFF9E .absSeg5

 

vector table I have commented just to see how much size it occupies. Vector 49 should be from FF9C to FF9D as per the datasheet

 

void (* const _vectab[])() @0xff9c = {
