capabilities of the processor.

 

● Idle Power Savings—Extended/Normal. Allows certain operating systems to decrease the

 

processors power consumption when the processor is idle.

repeated cycles of 3 blinks and a pause.

 

◦

S4 = 4 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (green LED) —

 

 

repeated cycles of 4 blinks and a pause.
