Dear expert:

I have been studying how to reduce the power consumption of DM3730 recently, and try to test the power off the IVA module and wake it up, I just refer to the Chapter 5 in DM3730 datesheet ,I don't understand the whole power off and wake up process very well, my question is how can i find the IVA power off and wake up demo code ?

Chenguang,

Unfortunately, I can not suggest you example source code but you can follow instructions in TRM about programming sequence and setting described register values.
