Function
This function is to change data rate(DR) by register setting
Settable data rate：10,80,160,320mS
This function is to output result which averaged measure value by designated number of times. (4, 8, 16
times)
When moving average is selected, internal sampling cycle becomes 5mS and data rate will be
determined by 5mS×average number of times.
