-/****************************************************************************
-**
-** Name: crt0ram.S
-**
-** Description:
-** Implements boot-code that calls LatticeDDInit (that calls main())
-** Implements exception handlers (actually, redirectors)
-**
-** $Revision: $
-**
-** Disclaimer:
-**
-** This source code is intended as a design reference which
-** illustrates how these types of functions can be implemented. It
-** is the user's responsibility to verify their design for
-** consistency and functionality through the use of formal
-** verification methods. Lattice Semiconductor provides no warranty
-** regarding the use or functionality of this code.

-** Change History (Latest changes on top)
-**
-** Ver Date Description
-** --------------------------------------------------------------------------
-** 3.8 Apr-15-2011 Added __MICO_USER_<handler>_HANDLER__ preprocessor to
-** allow customers to implement their own handlers for:
-** DATA_ABORT, INST_ABORT
-**
-** 3.1 Jun-18-2008 Added __MICO_NO_INTERRUPTS__ preprocessor
-** option to exclude invoking MicoISRHandler
-** to reduce code-size in apps that don't use
-** interrupts
-**
-** 3.0 Mar-25-2008 Added Header
