-- Purpose:
-- Feature test for retransmitt limitation
--
--------------------------------------------------------------------------------
-- Revision History:
-- 30.6.2016 Created file
-- 06.02.2018 Modified to work with the IP-XACT generated memory map
-- 12.06.2018 Modified to use CAN Test lib instead of direct register
-- access functions.
