Exception Processing Overview
ColdFire processors support a 1024-byte vector table aligned on any 1-Mbyte address
boundary; see Table 2-18. The table contains 256 exception vectors where the first 64 are
defined by Motorola; the remaining 192 are user-defined interrupt vectors.

fixed-length stack frame for all exceptions. The exception type determines whether
the program counter in the exception stack frame defines the address of the faulting
instruction (fault) or of the next instruction to be executed (next).
The exception vector table is aligned on a 1-Mbyte boundary. This instruction
address is obtained by fetching a value from the table at the address defined in the
vector base register. The index into the exception table is calculated as
4 x vector_number. When the index value is generated, the vector table contents
determine the address of the first instruction of the desired handler. After the fetch
of the first opcode of the handler is initiated, exception processing terminates and
normal instruction processing continues in the handler.
