Abstract

An apparatus, protocol and methods for reducing vehicle energy consumption and for precise electronic event control, by implementing full CPU off-loading, using pulse-width modulation (PWM) with analog feedback diagnosis enabling real-time operation. Accordingly, analog feedback is used for external integrated circuits (IC) controlled by a PWM output, for processes to be analyzed. The apparatus includes a microprocessor that integrates an autonomous PWM module and an analog-to-digital converter (ADC) group manager, each including register modules for enabling analog-to-digital signal conversion comparisons of PWM feedback data, and generating of an interrupt commands when required.
