Fast Ethernet Controller (FEC)
17.4.19 Transmit FIFO Watermark Register (TFWR)
The TFWR controls the amount of data required in the transmit FIFO before transmission of a frame can
begin. This allows you to minimize transmit latency (TFWR = 00 or 01) or allow for larger bus access
latency (TFWR = 11) due to contention for the system bus. Setting the watermark to a high value
minimizes the risk of transmit FIFO underrun due to contention for the system bus. The byte counts
associated with the TFWR field may need to be modified to match a given system requirement (worst case
bus access latency by the transmit data DMA channel).
17.4.20 FIFO Receive Bound Register (FRBR)
FRBR indicates the upper address bound of the FIFO RAM. Drivers can use this value, along with the
FRSR, to appropriately divide the available FIFO RAM between the transmit and receive data paths.

The GADDR2 register contains the lower 32 bits of the 64-bit hash table used in the address recognition process for
receive frames with a multicast address. Bit 31 of GADDR2 contains hash index bit 31. Bit 0 of GADDR2 contains
hash index bit 0.
Reserved, must be cleared.
