Abstract:
1. An analogue/digital conversion device comprising: a conversion sequence setting register in which an order analogue signals are converted when in a scanning mode during which a plurality of analogue signals are consecutively converted to digital signals is set; a multiplexer that selects sequentially a single analogue signal from said plurality of analogue signals, in an order that is set in said conversion sequence setting register; an analogue/digital converter that converts an analogue signal that is selected by said multiplexer to a digital signal and operable in the scanning mode for continuous A/D conversion of a plurality of input signals in a fixed order, and a select mode for individual A/D conversion of any desired input signal with any desired timing; and a conversion result register having a plurality of storage regions, that stores a digital signal obtained as a result of a conversion by said analogue/digital converter in storage regions in an order with which conversion was effected.
