PRODUCTION DATA
the device uses a cyclic redundancy check (CRC) to ensure data integrity for the configuration of the device while the driver output is active, the SPI communications (both transmitted and received), and the internal non-volatile memory that store the trim information that ensures the performance of the device. The CRC represents the remainder of a process analogous to polynomial long division, where the protected data is divided by the polynomial. The device uses the CRC8 polynomial X8 + X2 + X + 1 with a 0xFF initialization (to catch leading 0 errors) for its calculations.
