ALM_SMPL2 Register Definition
Address
0x27, 0x26
1
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
register are nonvolatile.

ALM_CTRL Register Definition
Address
0x29, 0x28
1
The ALM_CTRL register contains the alarm control variables.
Default is valid only until the first register write cycle.
Format is established by source of monitored data.
Default is valid only until the first register write cycle.
Default is valid only until the first register write cycle.
Description
Greater than Active Alarm Bit.
Not used.
Data Bits. This number can be either twos complement
or straight binary. The format is set by the value being
monitored by this function.
Description
