Note: Address lines A[0–23] hold their state after a read or write operation. AA[0–3] do not hold their
state after a read or write operation.
Bit 13 in the Operating Mode Register must be set to enter Asynchronous Arbitration mode.
Asynchronous Arbitration mode is recommended for operation at 100 MHz.
If Asynchronous Arbitration mode is active, none of the timings in Table 2-16 is required.
In order to guarantee timings 250, and 251, BG inputs must be asserted to different DSP56300 devices on the same bus in
the non-overlap manner shown in Figure 2-26.
