ABSTRACT:
An analog-to-digital conversion module and method minimize software involvement by providing a programmable control table comprising a plurality of conversion command words (CCW's). Each CCW designates conversion parameters such as channel and reference selection, input sample time, and re-sample inhibit for one conversion operation, upon conclusion of which a digital value is stored in a corresponding result table. A set of CCW's defines one or more conversion sequences. Upon conclusion of each sequence, an interrupt can be issued and the result table may be read by an associated device, such as a CPU. If desired, the CCW sequence may be dynamically altered during operation of the conversion system.
