5 Description:
6                 By default (value '0'), the capture thread checks for the Conversion
7                 Ready Flag to being set prior to committing a new value to the sample
8                 buffer. This synchronizes the in-chip conversion rate with the
9                 in-driver readout rate at the cost of an additional register read.
11                 Writing '1' will remove the polling for the Conversion Ready Flags to
12                 save the additional i2c transaction, which will improve the bandwidth
13                 available for reading data. However, samples can be occasionally skipped
14                 or repeated, depending on the beat between the capture and conversion
15                 rates.
