*
* @details
* QV_onIdle() is called by the cooperative QV kernel (from QF_run()) when
* the scheduler detects that no events are available for active objects
* (the idle condition). This callback gives the application an opportunity
* to enter a power-saving CPU mode, or perform some other idle processing
* (such as QS software tracing output).
*
* @note
* QV_onIdle() is invoked with interrupts **DISABLED** because the idle
* condition can be asynchronously changed at any time by an interrupt.
* QV_onIdle() MUST enable the interrupts internally, but not before
* putting the CPU into the low-power mode. (Ideally, enabling interrupts and
* low-power mode should happen atomically). At the very least, the function
* MUST enable interrupts, otherwise interrupts will remain disabled
* permanently.
