PHY ID Identifier Register 1 (PHYIDR1) -
Register 2
The PHY Identifier Registers 1 and 2 work together in
a single identifier of the NetPHY-1 device. The Identifier
consists of a concatenation of the
Organizationally
Unique Identifier
(OUI), a vendor's model number,
and a model revision number. The IEEE assigned OUI
is 00606E.
PHY Identifier Register 2 (PHYIDR2) -
Register 3
Bit
Bit Name
Default
Description
1.1
Jabber Detect
0,
RO/LH
Jabber Detect
:
1=Jabber condition detected.
0=No jabber condition detected.
This bit is implemented with a latching function. Once Jabber conditions
are detected this bit will remain set until a read operation is completed
through a management interface or a NetPHY-1 device reset. This bit
works only in 10 Mbps mode.
1.0
Extended
Capability
1,RO/P
Extended Capability
:
1=Extended register capable.
0=Basic register capable only.
Basic Mode Status Register (BMSR) -
Register 1
Bit
Bit Name
Default
Description
2.15-2.0
OUI_MSB
<0181H>
OUI Most Significant Bits
:
This register stores bits 3 - 18 of the OUI (00606E) to bits 15 - 0 of this
register, respectively. The most significant two bits of the OUI are ignored
(the IEEE standard refers to these as bit 1 and 2).
Bit
Bit Name
Default
Description
3.15-3.10
OUI_LSB
<101110>,RO/P
OUI Least Significant Bits
:
Bits 19 - 24 of the OUI (00606E) are mapped to bits 15 - 10 of this register,
respectively.
3.9-3.4
VNDR_MDL
<000000>,RO/P
Vendor Model Number
:
Six bits of the vendor model number mapped to bits 9 - 4 (most significant
bit to bit 9).
3.3-3.0
MDL_REV
<0001>,RO/P
Model Revision Number
:
Four bits of the vendor model revision number mapped to bits 3 - 0 (most
significant bit to bit 3).
