Hello, It is suggested to stop the automatic conversions because the register contents are updated based on when the channel is sampled, not when the register is read. This means that if you try reading a register content and a conversion occurs, the data could become corrupt. Having the host locked up brings in the dillema. Have you looked at the ADS7142 ? It has an Autonomous Mode with Post Alert Data; after an alert has been triggered, the device will store up to 16 entries after the alarm in a data buffer, the host can access the data once it is able to. Note the device does have tradeoffs from the ADS7924 functionality. When in Autonomous mode you will not be able to read the data out, not until a triggering event, the device in manual mode can provide data out for each conversion. Regards, Cynthia
