ABSTRACT:
A method and apparatus for performing power on reset initialization in a data processing system (40). In one form, the present invention uses a circuit (71) to ensure that a node (65) always power up to the correct logic level. This node (65) can then be used to initialize a latch (83) so that the latch (83) always drives a predetermined logic level at its data output when the latch (83) powers up. The data output of latch (83) is a Power On Reset signal which is asserted during power on reset initialization and which is negated when power on reset initialization is completed.
