DMA transaction (ADC-->Memory) with AmuxHW switch

[Anonymous]

I'd like to make DMA transfer 2 data from SAR ADC to Memory as switching AmuxHW, but the output of DAC was mixed signal of 2 data (reference to attached picture:Blue= SIG1, Yellow=SIG2, Green=output of DAC). 

   

Digital delay circuit was referenced to CE95299 (http://www.cypress.com/documentation/code-examples/ce95299-delta-sigma-adc-using-16-multiplexed-sing...).
