The MPC561/MPC563 samples the CR line at the rising edge of CLKOUT. When this signal is asserted,
the reservation flag is reset (negated).
The external bus interface (EBI) samples the logical value of the reservation flag prior to externally
starting a bus cycle initiated by the RCPU stwcx instruction. If the reservation flag is set, the EBI begins
with the bus cycle. If the reservation flag is reset, no bus cycle is initiated externally, and this situation is
reported to the RCPU.
The reservation protocol for a multi-level (local) bus is illustrated in
situation in which the reserved location is sited in the remote bus.
