BF561 Dual ADCs with PPI interface

Hi, 

I want to get  2  synchronous 14bits-ADC datas, one channel is connected with the PPI0 interface working on coreA,the PPI0_CLK is connected to Timer0,another channel is connected with the PPI1 interface working on coreB,the PPI1_CLK is connected to Timer7,  when I send the command to the BF561, I need to enable the PPI0 and the PPI1  working simultaneously, but I only get the PPI0 datas,the PPI1 can not work at the same time.   

Is the DMA controller can not control two PPIs simultaneously?   Can you help me to find out my problem?  Thank you.
