PRODUCTION DATA.
This register powers down individual channels that are not included for sequencing in AUTO_RST mode. The default value for this register is 00h, which implies that in default condition all channels are powered up. If all channels are powered down (that is, the value for this register is FFh), then the analog front-end circuits for all channels are powered down and the output of the ADC contains invalid data. If the device is in MAN-Ch_n mode and the selected channel is powered down, then the device yields invalid output that can also trigger a false alarm condition.
