TX FIFO Size (TX_FIF_SZ).
Sets the size of the TX FIFOs in 1KB values
to a maximum of 14KB. The TX Status FIFO consumes 512 bytes of the
space allocated by TX_FIF_SIZ, and the TX data FIFO consumes the
remaining space specified by TX_FIF_SZ. The minimum size of the TX
FIFOs is 2KB (TX data and status combined). The TX data FIFO is used for
both TX data and TX commands.
The RX Status and data FIFOs consume the remaining space, which is
equal to 16KB – TX_FIF_SIZ. See section
5.3.9.1 Allowable settings for
Configurable FIFO Memory Allocationon page 82
for more information.

Threshold Control Bits (TR).
These control the transmit threshold values
the MIL should use. These bits are used when the SF bit is reset. The host
can program the Transmit threshold by setting these bits. The intent is to
allow the MIL to transfer data to the final destination only after the threshold
value is met.
In 10Mbps mode (TTM = 1) the threshold is set as follows:
In 100Mbps mode (TTM = 0) the threshold is set by as follows:

PHY Clock Select (PHY_CLK_SEL).
This field is used to switch between
the internal and external MII clocks (RX_CLK and TX_CLK). This field is
encoded as follows:
[6] [5] MII Clock Source
---------------------------------------------------
0 0 Internal PHY
0 1 External MII Port
1 0 Clocks Disabled
1 1 Internal PHY
Notes:
■
This field does not control multiplexing of the SMI port or other MII signals.
■
There are restrictions on the use of this field. Please refer to
Section 3.12,
"MII Interface - External MII Switching," on page 43
for details.
