IP113M LF-DS-R11
MII
NAME
R/W
DESCRIPTION
DEFAULT
MII control register (address 00h)
0.9
Restart Auto-
Negotiation
RW
1 = re-starting Auto-Negotiation
0 = Auto-Negotiation re-start complete
Setting this bit to logic high will cause IP113M LF
to restart an Auto-Negotiation cycle, but depend on
the value of bit 0.12 (Auto-Negotiation Enable). If
bit 0.12 is cleared then this bit has no effect, and
change to Read Only. When an Auto-Negotiation
cycle is being processed, write 0 into this bit has
no
effect.
This
bit
is
self-clearing
after
Auto-Negotiation process is completed.
0
0.8
Duplex mode
R/W
1 = full duplex
0 = half duplex
It is valid only if bit 0.12 is set to be 0.
Pin(1)
0.7
Collision test enable
R/W
1 = enable the collision test
0 = disable the collision test
If setting this bit to logic 1, when MII TXEN signal is
asserted, IP113M LF will assert the MII COL signal
within 512BT (Bit Time, depend on 10Mbps or
100Mbps). When MII TXEN is de-asserted, then
TP110 will assert MII COL signal within 4BT.
Clearing this bit to logic 0 for normal operation
0
0[6:0]
