+ Optional, When hardware design introduces significant sensor data noise,
+ performance can be improved by adjusting register settings, including
+ but not limited to sample integration time and average sample count.
+ Performance tuning parameters represented as register address-value pairs.
+ The array consists of 8-bit values, where each pair represents a register
+ address followed by the value to be written to that register.
