1. Bit 13 in the OMR register must be set to enter Asynchronous Arbitration mode
2. At 100 MHz it is recommended to use Asynchronous Arbitration mode.
3. If Asynchronous Arbitration mode is active, none of the timings in
4. In order to guarantee timings 250, and 251, it is recommended to assert BG inputs to different 56300 devices (on the
