You need a lot more than this.....
SPI, is _only_ a description of a signalling standard, not a 'protocol'. Even as a signalling standard, there will be several more parts to the definition (MODE, and speed). Without these, you have no hope of decoding data. The same applies for PCM. There will then be protocols used _over_ these interfaces. You have perhaps 1/10th the information needed to start approaching talking over these interfaces...
Nbody is going to write you a complete program to interface between these, even when you have all the data. We will help, if there is a particular part, but you will need to write the program yourself.
