ABSTRACT:
A single--chip microcomputer recovers efficiently from the power-down state by means of an interrupt that bypasses RAM initialization. It the power supply fails in the power-down mode, restoration of the power supply later causes the microcomputer to reset and initialize its RAM contents.
