9.5.7.4
The MPC561/MPC563 can be configured at system reset to use the internal bus arbiter. In this case, the
MPC561/MPC563 will be parked on the bus. The parking feature allows the MPC561/MPC563 to skip the
bus request phase, and if BB is negated, assert BB and initiate the transaction without waiting for BG from
the arbiter.
The priority of the external device relative to the internal MPC561/MPC563 bus masters is programmed
in the SIU module configuration register. If the external device requests the bus and the MPC561/MPC563
does not require it, or if the external device has higher priority than the current internal bus master, the
MPC561/MPC563 grants the bus to the external device.
