Name of Exception
The 8 Kbytes allocated for the original PowerPC ISA exception table can be
almost fully utilized. This is possible if the MPC561/MPC563 system
memory is not mapped to the exception address space, (i.e., the addresses
0xFFF0 0000 to 0xFFF0 1FFF are not used).
In such case, these 8 Kbytes can be fully utilized by the compiler, except
for the lower 64 words (256 bytes) which are dedicated for the branch
instructions.
If the RCPU, while executing an exception, issues any address between two
successive exception entries (e.g., 0xFFF0 0104), then the operation of the
MPC561/MPC563 is not guaranteed if the ETR is enabled.
