In the power down mode the oscillator is stopped, and the instruction that invokes power down is the last instruction executed. The on-chip RAM and Special Function Regis- ters retain their values until the power down mode is termi- nated. The only exit from power down is a hardware reset. Reset redefines the SFRs but does not change the on-chip RAM. The reset should not be activated before Vcc is restored to its normal operating level and must be held active long enough to allow the oscillator to restart and sta- bilize.
