3.1.1
Device Serial Number Registers
A unique serial number is programmed into the serial number registers of each MMA68xx device during manufacturing. The
serial number is composed of the following information:
Bit Range
S12 - S0
S31 - S13
Content
Serial Number
Lot Number
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 13-bit serial number. Depending on
lot size and quantities, all possible lot numbers and serial numbers may not be assigned.
The serial number registers are included in the OTP shadow register array CRC verification. Reference Section 3.2.1 for de-
tails regarding the CRC verification. Beyond this, the contents of the serial number registers have no impact on device operation
or performance, and are only used for traceability purposes.
3.1.2
Reserved Registers
These reserved registers are read-only and have no impact on device operation or performance.

Self-Test Magnitude Selection Bits (STMAG_Y, STMAG_X)
The self-test magnitude selection bits indicate if the nominal self-test deflection value is set to the low or high value as shown
in the table below. The Self-Test Magnitude is selected independently for each axis.
