Randomized Lot Identification Bits
As an optional feature, Zilog is able to provide a factory-programmed random lot
identifier. With this feature, all devices in a given production lot are programmed with the
same random number. This random number is uniquely regenerated for each successive
production lot and is not likely to be repeated.
The randomized lot identifier is a 32 byte binary value, stored in the Flash information
page (see
on page 166 for more details) and is unaffected by mass erasure of the device's Flash
memory.
The following code example shows how to read data from the Flash information area.
; get value at info address 60 (FE60h)
ldx FPS, #%80 ; enable access to flash info page
ld R0, #%FE
ld R1, #%60
ldc R2, @RR0 ; R2 now contains the calibration value
The Trim Bit Address (TRMADR) register contains the target address for an access to the
trim option bits
