DESCRIPTION
Organizationally Unique Identifier:
TERIDIAN Semiconductor Corporation. This register contains the first
16-bits of the identifier.
DESCRIPTION
Organizationally Unique Identifier: Remaining 6 bits of the OUI.
Model Number: The last 2 digits of the model number 78Q2123 are
encoded into the 6 bits for both 78Q2123 and 78Q2133.
Revision Number:
revision of the silicon.
Remote Fault: A logic one indicates that a remote fault condition has
been detected and it remains set until it is cleared. This bit can only
be cleared by reading this register (MR1) via the management
interface.
Auto-Negotiation Ability:
ability to perform Auto-Negotiation. The value of this bit is determined
by the ANEGEN bit (MR0.12).
Link Status:
established. If the link status should transition from an OK status to a
NOT-OK status, this bit will become cleared and remains cleared until
it is read.
Jabber Detect: In 10Base-T mode, this bit is set during a jabber
event. After a jabber event, the bit remains set until cleared by a read
operation.
Extended Capability:
provide an extended register set (MR2 and beyond).
