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.
