Can we connect I2S lines in the arm M0? If so any references??

Yes there are Cortex ARM M0 chips that have an I2S interface, Google's first return for 'ARM M0 I2S" was http://www.nxp.com/documents/leaflet/75017550.pdf but that is just a random first response and there seems to be lots of them. The ARM M0 itself is just a processor core, there are lots of other things on the chips including interfaces like this one which would be connected to its peripheral bus.
I am working with nordic nrf51822...I was trying to see if I can connect the I2S lines of a MEMS microphone to the SoC. I don't see any direct I2S lines on the chip. Is there any alternate way?
Perhaps some GPIO lines could be used? The processor is probably powerful enough to do the job without special hardware for buffering. I'd be inclined to search around and see if there is some Arduino or Raspberry Pi project that does the sort of thing you are interested in, it sounds like the sort of thing somebody has probably done.
