Register Description: The default value of 0x072 represents 114 eight-byte locations. This
equates to 912 bytes of data. A unit entry in this register equates to 8 bytes of data. When the
amount of data stored in the RX FIFO falls below the Low Watermark, flow control is
automatically de-asserted within the MAC to allow more line-side data to be captured by the
RX FIFO.
