HCS08SL::Software Realization of SPI interface

[Destiny]

Dear Friends
         Did anybody tried for a software realisation of SPI interface?? Can anybody give me a hint how to proceed with it.
        The background is that we are having a interface of HCS08SL with a DAC (Analog device:AD5641) through an SPI (Master mode) connection. I need this software realisation of SPI since the one available with HCS08SL is already in use and cant be used for the DAC interface.
          Please help me!!

Here's one example (in assembly).  You'll need to modify for different polarity and phase settings.
