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.
