Alarm Registers
The alarm function provides monitoring for two independent
conditions. The ALM_CTRL register provides control inputs
for data source, data filtering (prior to comparison), static
comparison, dynamic rate-of-change comparison, and output
indicator configurations. The ALM_MAGx registers establish
the trigger threshold and polarity configurations. Table 30 gives
an example of how to configure a static alarm. The ALM_SMPLx
registers provide the number of samples to use in the dynamic
rate-of-change configuration. The period equals the number in
the ALM_SMPLx register multiplied by the sample period time,
which is established by the SMPL_PRD register. See Table 31 for
an example of how to configure the sensor for this type of function.

PRODUCT IDENTIFICATION
Table 32 provides a summary of the registers that identify
the product: PROD_ID, which identifies the product type;
LOT_ID1 and LOT_ID2, the 32-bit lot identification code;
and SERIAL_NUM, which displays the 12-bit serial number.
All four registers are two bytes in length. When using the
SERIAL_NUM value to calculate the serial number, mask
off the upper four bits and convert the remaining 12 bits to
a decimal number.
