These serial numbers are stored in the Flash information page and are unaffected by mass
erasure of the device's Flash memory. See the Reading the Flash Information Page section
below and
Randomized Lot Identification Bits
As an optional feature, Zilog is able to provide a factory-programmed random lot identi-
fier. 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 produc-
tion lot and is not likely to be repeated.
The randomized lot identifier is a 32 byte binary value, stored in the Flash information
page and is unaffected by mass erasure of the device’s Flash memory. See Reading the
Flash Information Page, below, and
more details.
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
This section briefly describes the features of the Trim Bit Address and Data registers.
The Trim Bit Address (TRMADR) Register contains the target address for an access to the
trim option bits (Table 86).
