LOW POWER ABOUT 5510

Hello,everyone.I have a problem about 5510's LOW POWER.

Acorrding to the datasheet,there are six idle domains.The DSP will be in idle mode if we write 1 into the bits and the lowest current is 1mA.

NOW the question is that I write 1 to the fifth to zero bit of the ICR,but I get 70mA.

By the way, there is a bit of IDLEEN in Mcbsp's and timer's register and I also set it 1.the result is 70mA.

I have no idea whether or not my source is correct. Please help me if you have done this or understand it .

much more appreciated,if offer the source.

thank you.
