7.7.28 Device serial number registers
The serial number registers are factory programmed OTP registers that include the
unique serial number of the device. Serial numbers begin at 1 for all produced devices
in each lot and are sequentially assigned. Lot numbers begin at 1 and are sequentially
assigned. No lot will contain more devices than can be uniquely identified by the 14-bit
serial number. Depending on lot size and quantities, all possible lot numbers and serial
numbers might not be assigned. These registers are included in the factory programmed
OTP array error detection. These registers are readable in SPI mode or I2C mode when
ENDINIT is not set.
