Section 4 Exception Handling
4.1.3
Before exception handling begins, the exception vector table must be written in memory. The
exception vector table stores the start addresses of exception service routines. (The reset exception
table holds the initial values of PC and SP.)
All exception sources are given different vector numbers and vector table address offsets, from
which the vector table addresses are calculated. In exception handling, the start address of the
exception service routine is fetched from the exception vector table as indicated by the vector table
address.
Table 4.3 lists the vector numbers and vector table address offsets. Table 4.4 shows vector table
address calculations.
