8.5.3.7 WREG (0100 rrxx dddd dddd)

The WREG command writes dddd dddd to the register at address rr. Multiple registers can be written within the same I²C frame by simply issuing another WREG command without providing a STOP condition following the previous register write. Figure 59 shows the sequence for writing an arbitrary number of registers. The R/W bit at the end of the address byte is 0 to indicate a write. The WREG command forces the digital filter to reset and any ongoing ADC conversion to restart.
