5.4.1 EXCEPTION VECTORS
Exception vectors are memory locations from which the
CPU fetches the address of a routine that will handle that
exception. All exception vectors are 2 words long (see Fig.6)
except for the reset vector which is made up of 4 words,
containing the Program Counter (PC) and the
Supervisor Stack Pointer (SSP). All exception vectors are
contained in the supervisor data space.
A vector number is an 8-bit number that, when multiplied
by 4, gives the address of an exception vector. Vector
numbers are generated internally. The memory map for
the exception vectors is given in Table 2.
