Specifications
The asynchronous bus arbitration is enabled by internal synchronization circuits on
synchronization circuits add delay from the external signal until it is exposed to internal logic. As a result of this
delay, a DSP56300 part may assume mastership and assert
reason for timing 250.

Therefore, some non-overlap period between one
ensures that overlaps are avoided.
