Bit	Name	Description	Type1	Default

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				0x0E6
amount of data stored in the RX FIFO exceeds the high watermark, flow control is				0x0E6

automatically initiated within the MAC to avoid an overflow condition.

Bit	Name	Description	Type1	Default

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				0x072
automatically de-asserted within the MAC to allow more line-side data to be captured by the
RX FIFO.
