5.1.3
Before exception processing begins running, the exception processing vector table must be set in
memory. The exception processing vector table stores the start addresses of exception service
routines. (The reset exception processing 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 processing, the start addresses of the exception service routines are fetched from
the exception processing 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.
