1 Default is valid only until the first register write cycle.

The ALM_SMPL2 register contains the sample period information

for Alarm 2, when it is set for ROC alarm monitoring. The ROC

alarm function averages the change in the output variable over the

specified number of samples and compares this change directly to

the values specified in the ALM_MAG2 register. The contents of this
