| | //**IP control and data ports**// |||| | | //**IP control and data ports**// |||| |
| | DATA_O | OUT | 16 | Outputs the data read from the ADC. The channel ID is stored on the 4 most significant bits and the read data is stored on the 12 least significant bits. If the ADC is driven in word read mode then the channel ID will always be 0. | | | DATA_O | OUT | 18 | Outputs the data read from the ADC. | |
| | DATA_RD_READY_O | OUT | 1 | Active high signal to indicate the status of a read operation from the AD7982. The IP continuously reads the conversion results from the ADC and outputs them on the DATA_O bus. When this signal is high data can be read from the DATA_O bus. | | | DATA_RD_READY_O | OUT | 1 | Active high signal to indicate the status of a read operation from the AD7982.

| | ADC_CNV_O | OUT | 1 | ADC Convert Input. This input has multiple functions. On its leading edge, it initiates the conversions and selects the interface mode of the part, chain, or CS mode. In CS mode, it enables the SDO pin when low. In chain mode, the data should be read when CNV is high. | | | ADC_CNVST_O | OUT | 1 | ADC Convert Input. This input has multiple functions.
