3.6.9.3
In ABR-ER mode, one connection entry requires two AVT Context RAM sections with a
total of 8 double words. Since the AVT table is accessed from the external micro
controller via a 16-bit transfer register, the ABR-ER connection context appears as a
16-bit organized table with 16 entries as shown in
Assuming that each bi-directional ABR connection has two sides, A and B, and the
upstream core is handling traffic from A->B and the downstream core is handling traffic
from B->A; then, parameters with suffix b denote direction A->B, and parameters with
suffix f denote direction B->A.
