Hello Lung,

On every TM4C device, the register DID0 and DID1 in System Control module help identify the device class and package related information. Besides that on TM4C129x there is UNIQUEID0-UNIQUEID3 register in System control module which can help identify each device of the family,

Thank you very much.
And what command line can read the register in CCS, I guess it is special.
