Description
This field defines the version of the DID1 register format:
0=Register version for the Stellaris microcontrollers
Family
This field provides the family identification of the device
within the Luminary Micro product portfolio.
The 0x0 value indicates the Stellaris family of
microcontrollers.
Part Number
This field provides the part number of the device within the
family.
The 0x17 value indicates the LM3S317 microcontroller.
Reserved bits return an indeterminate value, and should
never be changed.
Temperature Range
This field specifies the temperature rating of the device. A
value of 1 indicates the industrial temperature range (-40°C
to 85°C).
This field specifies the package type. A value of 1 indicates
a 48-pin LQFP package.
RoHS-Compliance
A 1 in this bit specifies the device is RoHS-compliant.
