ABSTRACT:
An analog-to-digital conversion module, QADC (1), and method minimize software involvement by providing a pause capacility. Each queue in the QADC (1) has one or more Conversion Command Words, CCWs (82), in a Conversion Command Word Table (62). Each conversion command word, CCW (82), has a Pause bit which can be used to create multiple sub-queues of A/D conversions without requiring the use of interrupts. The Pause bit can be used to place a queue in a pause state. When a queue enters a pause state, the scanning of CCWs (82) is stopped. The queue must then receive a trigger in order for the scanning of CCWs (82) to continue again.
