Datasheet
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-ms 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.
