-- Purpose:
-- Feature test for frame transmittion with invalid configurations
-- Feature test for frame transmittion with invalid combination of configu
-- rations.
--
--------------------------------------------------------------------------------
-- Revision History:
--
-- 30.6.2016 Created file
-- 06.02.2018 Modified to work with the IP-XACT generated memory map
-- 12.6.2018 Modified to use CAN Test lib instead of direct register
-- access functions.
