Central Processing Unit
operating system should set the RI bit in the MSR at the end of each exception handler’s prologue (after
saving the program state) and clear the bit at the start of each exception handler’s epilogue (before
restoring the program state). Then, if an unordered exception occurs during the servicing of an exception
handler, the RI bit in SRR1 will contain the correct value.
3.11.4
In the RCPU, all synchronous (instruction-caused) exceptions are precise. When a precise exception
occurs, the processor backs the machine up to the instruction causing the exception. This ensures that the
machine is in its correct architecturally-defined state. The following conditions exist at the point a precise
exception occurs:
3.11.5
The setting of the exception prefix (IP) bit in the MSR determines how exceptions are vectored. If the bit
is cleared, the exception vector table begins at the physical address 0x0000 0000; if IP is set, the exception
vector table begins at the physical address 0xFFF0 0000.

Exception Vector Table
In the MPC561/MPC563, the exception table can additionally be relocated
by the BBC module to internal memory and reduce the total size required by
