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-218x DSP Hardware Reference, for BR/BG cycle relationships.
BGH is asserted when the bus is granted and the processor requires control of the bus to continue.
