78Q2123/78Q2133 MicroPHY™  
10/100BASE-TX Transceiver  
MR1: Status Register (continued)  
BIT  
SYMBOL TYPE DEFAULT DESCRIPTION  
1.4  
RFAULT  
RC  
0
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.

0
Auto-Negotiation Ability: When set, this bit indicates the device’s  
ability to perform Auto-Negotiation. The value of this bit is determined  
by the ANEGEN bit (MR0.12).  
Link Status: A logic one indicates that a valid link has been  
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.  
EXTD  
Extended Capability: Reads ’1’ to indicate the 78Q2123/78Q2133  
provide an extended register set (MR2 and beyond).

RN  
R
07h  
Revision Number: The value ‘0111’ corresponds to the seventh  
revision of the silicon.
