They are driven/read simult aneous ly on the external AD bus.

Page 273

MPC5200B Users Guide, Rev . 1 9-8 F reescale Semiconductor Modes of Operation The MUXed mode requires exter nal logic to latch the address during the address tenure and to decode bank selects if they are en coded. This mode is slower than the non-MUXed mode be cause data and address are multiplexed in time.
