in 52832,if only use 32M oscillator the power dissipation is about 600uA,if use both 32M and 32.768khz,the power dissipation is about 2.2uA. why?

I do not think this is possible with any SoC technology we have or will have in the near future. I am pretty sure that you do not have 32M clock running when you get 2.2uA reading.
