5.1.3
Before exception handling starts, the exception handling vector table must be set in memory. The
exception handling vector table stores the start addresses of exception handling routines. (The
reset exception handling table holds the initial values of PC and SP.)
All exception sources are given different vector numbers and vector table address offsets. The
vector table addresses are calculated from these vector numbers and vector table address offsets.
During exception handling, the start addresses of the exception handling routines are fetched from
the exception handling vector table that is indicated by this vector table address.
Table 5.3 shows the vector numbers and vector table address offsets. Table 5.4 shows how vector
table addresses are calculated.
