I want to use a code in Energia when I was editing CCS example code
But, i got a message like this.
-------------------------------------------------------------
sketch_jan06c.cpp: In function 'int main()':
sketch_jan06c.cpp:82:33: error: '_bis_SR_register' was not declared in this scope
-------------------------------------------------------------------------
How can i do?
