[bit31:16] ARBA[15:0] : Upper Half of Asynchronous Receive Base Address for DMA
mode
These bits allow system software to define the base address (ARBA[31:16]) for asynchronous receive
system memory buffers.
This base address is shared by all asynchronous receive channels and defines the upper 16 bits of the
32-bit system bus address for these channels.
This bit field is only used in DMA mode. In IO mode these bits are not used.
