1. With no external access from the DSP56156
2. During external read or write access
3. During external read-modify-write access
4. During Stop mode — external bus is released and BG is always low
5. During Wait mode
6. With external accesses pending by the DSP56156
7. Slave mode, when bus is still busy after bus request has been deasserted
