Grant state the SLP# signal can be asserted, causing the
processor to enter the Sleep state. The SLP# signal is not
recognized in the Normal state or the Auto Halt state.
The processor can be reset by the RESET# signal while in
the Sleep state. If RESET# is driven active while the
processor is in the Sleep state, then SLP# and STPCLK#
must immediately be driven inactive to ensure that the
processor correctly initializes itself.
Input signals (other than RESET#) may not change while the
processor is in the Sleep state or transitioning into or out of
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.
4.4.8
Deep Sleep State
The Deep Sleep state is the lowest power mode the
processor can enter while maintaining its context. Stopping
the BCLK input to the processor enters the Deep Sleep
state, while it is in the Sleep state or the 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 the Quick
Start state from the Deep Sleep state when the BCLK input
is restarted. Due to the PLL lock latency, there is a 30-
millisecond 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.
