#80804 - Bit-Bang it
Responding to: ???'s previous message
"Bit Banging" means driving the lines directly from software:

In your case, this should not be difficult.
Diagramm 1 in the Data Sheet shows you the waveforms that you need to generate: the clock (SCLK), USTAB, and SLE are easy; SDATA is just a matter of applying the appropriate bit value at the correct time in relation to SCLK.

Quite likely, the precise widths of the SCLK high & low periods are non-critical; the important bit is probably just setting SDATA at the correct time in relation to the SCLK edge.
You will have to read the data sheet yourself to check this out - my German isn't up to it:
