 **  Name: crt0ram.S
 **
 **  Description:
 **        Implements boot-code that calls LatticeDDInit (that calls main())
 **        Implements exception handlers (actually, redirectors)

 **  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
