Automatic A/D converter operation with selectable result format

摘要

An analog-to-digital conversion system and method provide selectable data formats for each converted digital result value. Each digital result is stored in a register or table word. Information from a host processor is used to select a desired data format. In one embodiment the address range used to read the digital result serves to select the appropriate data format option, which may be, for example, left-justified or right-justified data, and signed or unsigned data. In another embodiment, one or more command words from the processor are used to select the desired data format.
