the Sleep state. Input signal changes at these times will
cause unpredictable behavior. Thus, the processor is
incapable of snooping or latching any events in the Sleep
state.
While in the Sleep state the processor can enter its lowest
power state, the Deep Sleep state. Removing the
processor’s input clock puts the processor in the Deep Sleep
state. PICCLK may be removed in the Sleep state.
The Sleep state is not supported in Intel mobile modules.
4.4.8.
Deep Sleep State
The Deep Sleep state is the lowest power mode the
processor can enter while maintaining its context. The Deep
Stopping the BCLK input to the processor enters sleep state,
while it is in the Sleep state or Quick Start state. For proper
operation, the BCLK input should be stopped in the low
state.
The processor will return to the Sleep state or Quick Start
state from the Deep Sleep state when the BCLK input is
restarted. Due to the PLL lock latency, there is a 30-msec
delay after the clocks have started before this state transition
happens. PICCLK may be removed in the Deep Sleep state.
PICCLK should be designed to turn on when BCLK turns on
when transitioning out of the Deep Sleep state.
The input signal restrictions for the Deep Sleep state are the
same as for the Sleep state, except that RESET# assertion
will result in unpredictable behavior.
