How can I use the analog inputs of ADuCM360 as logic input?

I use the DMA to sample two channels @2ksps. I have connected some logic outputs to the unused AIN1, AIN2 pins since I have used up all the GPIOS. What would be the best way to get the logic level besides using a one shot sampling wher the ADC have been changed to those channels. 

My question is : can I use the DETSTAT register to convert my unused AINx pins as logic inputs gaining speed or should I just sample normally on the cost of loosing samples on my principal analog signals?
