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.
