BR is an asynchronous signal. If BR meets the setup/hold requirements, it will be recognized during the current clock cycle; otherwise the signal will be recognized on
the following cycle. Refer to the ADSP-2100 Family User’s Manual, Third Edition for
BR/BG cycle relationships.

BGH is asserted when the bus is granted and the processor requires control of the bus to continue.
