MSP432P4111: Multiple ADC sample rates

Part Number:MSP432P4111

Hi

I am new to ARM development. I am currently developing a power critical application on the MSP432P4111, but the eventual target will be MSP430 based. I need to sample one ADC input at 250ms intervals, and then sample battery power and another channel at 1s intervals. I wish to wake up the processor only at 1s intervals to save power. 

I am unsure how to set up the ADC to do this, and also of the clock divider values to achieve these.
1. Can I configure the ADC to sample all of these independently for a 1s interval, and then use the DMA to transfer the six values to memory and then only wake up the processor to process once this is done? If this is not possible, what is the best alternative?
2. Will the same apply to the 430 family?

Thanks

Paul
