5.2 Die-ID Registers
The two registers (DIEIDL and DIEIDH) form a 64-bit number that contains information about the device’s
die lot number, wafer number and X, Y wafer coordinates. The die identification information will vary from
unit to unit. This information is programmed by TI as part of the initial device test procedure. The data
format of the Die-ID registers is shown here.
