V1.0 January, 30 2013:  In ths version a workoraound for the erratum PMU_CM.001
is implmented (patch for the Exception and interrupt handlers)
V1.1 Augsut, 17 2013:  Fix the bug of preprocessor due to workoraound for 
the erratum PMU_CM.001, and the bug of stack pointer alignment to a 8 byte boundary
