7.9.4
Only PGA gain settings can be changed dynamically while ADC conversions are in progress. When PGA gain settings are changed, the first
sample from the ADC is invalid. Ignore the first interrupt after the gain re-configuration. Valid data starts from the second interrupt onwards.

7.9.5 Configuring the Device During Normal Mode
Following registers can be programmed dynamically when the device is in operational mode (Normal mode).
During the operation (Normal mode) of the device, if any of the registers need to be programmed or changed other than the above mentioned
registers, then it is required to STOP the device by writing into MOD_CTL_REG “STOP” bit and configure the device as per the requirements and
start the device.
