Register Description: The value of this register follows the same scheme as the device
identification register found in the IEEE 1149.1 specification. The upper four bits correspond to
silicon stepping. The next 16 bits store a Part ID Number. The next 11 bits contain a JEDEC
manufacturer ID. Bit zero = 1 if the chip is the first in a stack. The encoding scheme used for
the Product ID field is implementation-dependent.
1. RO = Read Only, No clear on Read; R = Read, Clear on Read; W = Write only; R/W = Read/Write, No
2. These bits vary with stepping.
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
