Register Description: The default value of 0x0E6 represents 230 eight-byte locations. This
equates to 1840 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 exceeds the high watermark, flow control is
automatically initiated within the MAC to avoid an overflow condition.
1. RO = Read Only, No clear on Read; R = Read, Clear on Read; W = Write only; R/W = Read/Write, No
