NAME
R/W
DESCRIPTION
DEFAULT
MII status register (address 01h)
1.15
100Base-T4
capable
RO
1 = 100Base-T4 capable
0 = not 100Base-T4 capable
IP113M LF does not support 100Base-T4. This bit
is fixed to be 0.
0
1.14
100Base-X full
duplex Capable
RO
1 = 100Base-X full duplex capable
0 = not 100Base-X full duplex capable
The default of this bit will change depend on the
external setting of IP113M LF. If external pin
setting without 100Base-X full duplex support, then
this bit will change default to logic 0.
1
1.13
100Base-X half
duplex Capable
RO
1 = 100Base-X half duplex capable
0 = not 100Base-X half duplex capable
The default of this bit will change depend on the
external setting of IP113M LF. If external pin
setting without 100Base-X half duplex support,
then this bit will change default to logic 0
1
1.12
10Base-T full duplex
Capable
RO
1 = 10Base-T full duplex capable
0 = not 10Base-T full duplex capable
The default of this bit will change depend on the
external setting of IP113M LF. If external pin
setting without 100Base-T full duplex support, then
this bit will change default to logic 0
1
1.11
10Base-T half
duplex Capable
RO
1 = 10Base-T half duplex capable
0 = not 10Base-T half duplex capable
The default of this bit will change depend on the
external setting of IP113M LF. If external pin
setting without 100Base-X full duplex support, then
this bit will change default to logic 0

RO
1 = preamble may be suppressed
0 = preamble always required
1
1.5
Auto-Negotiation
Complete
RO
1 = Auto-Negotiation complete
0 = Auto-Negotiation in progress
When
read
as
logic
1,
indicates
that
the
Auto-Negotiation process has been completed,
and the contents of register 4, 5, 6 and 7 are valid.
When
read
as
logic
0,
indicates
that
the
Auto-Negotiation process has not been completed,
and the contents of register 4, 5, 6 and 7 are
meaningless. If Auto-Negotiation is disabled (bit
0.12 set to logic 0), then this bit will always read as
logic 0.
