Abstract
A method and system for generating an ignition coil output signal to control charging and discharging of a plurality of ignition coils in an internal combustion engine. A plurality of holding registers asynchronously receive a plurality of ignition coil data from a processor. The plurality of holding registers are memory-mapped and store the plurality of ignition coil data until subsequent ignition coil data is received from the processor. A sensor is provided for determining a position of the engine and generating a corresponding engine signal. A plurality of match registers are coupled to the plurality of holding registers for comparing the ignition coil data with a reference signal and generating an ignition coil output signal for receipt by one of the plurality of ignition coils based on the engine signal and the comparison between the ignition coil data and the reference signal.
