Using SPI and ICSP pins for external ADC and DAC (on Due)?

I am using the Arduino Due.

Is it possible to use the SPI and ICSP pins for two separate ADC and DAC? Or would I just have to use only the SPI (or ICSP) pins and just use different CS digital pins?

It seems like the ICSP and SPI pins have identical features (both have MISO, MOSI, GND, SCK, etc.). I plan on using the SPI library for both converters.

Sorry newbie here, any hints to do this would be helpful. :)

The ICSP just brings the same SPI pins out to a standard location. To use SPI for different peripherals use a separate CS line for each, as you have already figured out.

You won't be able to use both peripherals simultaneously whilst doing this of course as the data would get corrupted at the very least and at worst the peripherals would probably go off in a huff and refuse to speak to any Arduino for days, I know this to be true. :o
