1.10 Global Unique Identification Number (ID)

STC 1T MCU 12C5620AD series, each MCU has a unique identification number (ID). User can use “MOV @Ri”

instruction read RAM unit F1~F7 to get the ID number after power on. If users need to the unique identification

number to encrypt their procedures, detecting the procedures not be illegally modified should be done first.

//The following example program written by C language is to read internal ID number
