2.4.5.2 Asynchronous Bus Arbitration Timings
Freescale Semiconductor

Bit 13 in the Operating Mode Register must be set to enable Asynchronous Arbitration mode.
To guarantee timings 250 and 251, it is recommended that you assert non-overlapping BG inputs to different DSP56300
devices (on the same bus), as shown in Figure 2-12, where BG1 is the BG signal for one DSP56300 device while BG2 is the
BG signal for a second DSP56300 device.
Note: Address lines A[0–17] hold their state after a
read or write operation. AA[0–3] do not hold their
state after a read or write operation.
