Use SRU to invert SPI DS?

Question asked by apope on May 10, 2010

Is it possible on the 21371 to take an input pin like DAI 1, invert it and route it to SPIB DS?  The manual and engineering notes lead me to believe this is possible via MISCA4 or MISCA5, however, I cannot get the Expert SRU Code Generator tool to allow this.  Possibly this has something to do with the Group A-F and this combination is not possible, does there any other way besides using something external to the DSP?

 

Thanks,
