PRELIMINARY

Visual Status Display

LDA/B[4:0] and LDGA/B provide visual status indicators

for the eIMR. LDA/B[4:0] displays Link, Carrier Sense,

Collision, and Partition information for the TP and AUI

ports. LDGA/B display global Carrier Sense, Collision,

and Jabber information.

In a multiple eIMR configuration, the global LED drivers

(LDGA/B) from each chip can be tied together to drive

a single pair of global status LEDs. The open drain out-

put of these drivers facilitate this configuration. Refer to

Figure 13.
