Exception Sources and Exception Handling Vector Table

Different vector table address offsets are assigned to different exception sources. The vector table
addresses are calculated from the contents of the vector base register (VBR) and vector table
address offset of the vector number. The start address of the exception service routine is fetched
from the exception handling vector table indicated by this vector table address.
Table 4.2 shows the correspondence between the exception sources and vector table address
offsets. Table 4.3 shows the calculation method of exception handling vector table addresses.
Since the usable modes differ depending on the product, for details on the available modes, see
section 3, MCU Operating Modes.
