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 driv-
ers (LDGA/B) from each chip can be tied together to
drive a single pair of global status LEDs. The open drain
output of these drivers facilitate this configuration. Refer
to Figure 15.
