Abstract
A voltage monitoring method and apparatus starts with the operation of a normal microcomputer program flow, in a microcomputer (40). An input voltage source (90) is converted to a current digital output word (581) representative of the instantaneous amplitudes of the input voltage source (90). A threshold condition (562) is set ahead of time. When the current digital output word (581) satisfies the threshold condition (582), an interrupt signal (36) is generated. Finally, the normal microcomputer program flow is interrupted in response to the interrupt signal (36).
