AMDIX_EN Strap State. This read-only bit reflects the state of the
AMDIX_EN strap pin (pin 73). This pin can be overridden by PHY Registers

Must Be One (MBO). This bit must be set to “1” for normal device
operation.
TX FIFO Size (TX_FIF_SZ). Sets the size of the TX FIFOs in 1 kB values
to a maximum of 14 kB. 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 2 kB (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 16 kB – TX_FIF_SIZ. See
Configurable FIFO Memory Allocation," on page 94
Reserved
32/16-bit Mode. When set, the LAN89218 is set for 32-bit operation. When
clear, it is configured for 16-bit operation. This field is the value of the
D32/nD16 strap.
Soft Reset Time-out (SRST_TO). If a software reset is attempted when the
internal PHY is not in the operational state (RX_CLK and TX_CLK running),
the reset will not complete and the soft reset operation will time-out and this
bit will be set to a ‘1’. The host processor must correct the problem and
issue another soft reset.
