Chapter 4 Register Map and Descriptions Analog Input Register Group The two registers making up the Analog Input Register Group control the analog input circuitry and can be used to read the ADC FIFO. Reading from the ADC FIFO Register location transfers data from the AT-MIO-16X ADC FIFO buffer to the PC. Writing to the CONFIGMEM Register location sets up channel configuration information for the analog input section. This information is necessary for single conversions as well as single- and multiple-channel data acquisition sequences. Bit descriptions of the two registers making up the Analog Input Register Group are given on the following pages. © National Instruments Corporation 4-31 AT-MIO-16X User Manual
