PRODUCTION DATA.
The LDC1612/LDC1614 conversion data spans 2 registers. To avoid multi-conversion data corruption, the device uses an internal shadow register to hold conversion results for each channel. When a conversion completes, the corresponding internal shadow register is updated with the new conversion result. When the DATAx_MSB register is read, the contents of both the DATAx_MSB and DATAx_LSB registers are updated with the new conversion data.
Therefore, to correctly retrieve the conversion results for a given channel, the proper sequence is to first read the DATAx_MSB register, and then read the DATAx_LSB register.
