he NS9750 ASIC contains two busses that interconnect the peripherals. The high
speed peripherals reside on the AMBA AHB bus. The low speed peripherals reside on
the Digi proprietary BBus. The main function of the BBus bridge is to connect the
main AHB bus to the proprietary Digi BBus. Both bus interfaces have a master and a
slave interface.
