ColdFire Core
ColdFire processors support a 1024-byte vector table aligned on any 1-Mbyte address boundary; see
Table
remaining 192 are user-defined interrupt vectors.

3. The processor saves the current context by creating an exception stack frame on the system stack.
4. The processor acquires the address of the first instruction of the exception handler. The exception
2-18. The table contains 256 exception vectors where the first 64 are defined by Freescale; the
ColdFire processors support a single stack pointer in the A7 address register; therefore, there is no
notion of separate supervisor and user stack pointers. As a result, the exception stack frame is
created at a 0-modulo-4 address on the top of the current system stack. Additionally, the processor
uses a simplified 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).
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.
