Functional Description
3.6.9.2 AVT Context RAM Section for ABR-VS/VD Support
In ABR-VS/VD mode, one connection entry requires two AVT Context RAM sections with
a total of 8 double words (of 32-bit width each). Since the AVT table is accessed from
the external micro controller via a 16-bit transfer register, the ABR-VS/VD connection
context appears as a 16-bit organized table with 16 entries as shown:
