Define Documentation

#define CPU_IDLE   do { /* nothing */ } while (0)

Invoked by the scheduler to stop the CPU when idle.

This hook can be redefined to put the CPU in low-power mode, or to profile system load with an external strobe, or to save CPU cycles in hosted environments such as emulators.
