XCore DevWaitForInterrupt

This part defines the function WaitForInterrupt(). XCore defines the empty variant of this function, but Target may override this definition. This function stops CPU until some interrupt is asserted. Usually it is implemented using assembler.

/* DevWaitForInterrupt.h */

#ifndef CCore_inc_dev_DevWaitForInterrupt_h

namespace CCore {

void WaitForInterrupt();

Here is an implementation for ARMv7:
