我最近在用Xmega实现ADC以及温度检测的的功能，datasheet中说要从signature row中读取数据，查了很多资料，都说下面几个步骤：
The Read User Signature Row and Red Calibration Row commands are used to read one byte
from the User Signature Row or Calibration Row.
1. Load the Z-pointer with the byte address to read.
2. Load the NVM CMD register with the Read User Signature Row / Calibration Row
command
3. Execute the LPM instruction.
The destination register will be loaded during the execution of the LPM instruction
太抽象了，不好理解！
有没有文明做过相关的东西！给点example or advice!
thanks!
