Section 4 Exception Handling
4.1.3
Exception Vector Table
Before exception handling can execute, the exception vector table must be set in memory. The
exception vector table holds the start addresses of exception handling routines (the table for reset
exception handling stores initial PC and SP values). Different vector numbers and vector table
address offsets are assigned to different exception sources. The vector table addresses are
calculated from the corresponding vector numbers and vector address offsets. In exception
handling, the exception handling routine start address is fetched from the exception vector table
indicated by this vector table address.
Table 4.2 lists vector numbers and vector table address offsets. Table 4.3 shows how vector table
addresses are calculated.
