Using Kinetis SPI without SIN

[myke_predko]

I'm using a SPI port to write data to just an OLED display, there is no SPI data output that I would connect to the SPI SIN - currently I'm tying the pin to VSS.  

So, the obvious question is, could I use the pin I've allocated for SIN as a DI/DO and ignore what happens inside the chip?  Reading the RM, I don't see how this could be a problem, but I thought I'd ask the wise people here.

Hi,

If the SIN do not influence the communication between the master and slave, you can ignore it. And use it as general IO. 

Have a great day,

Thank you - it's nice getting the extra pin.  

Have a great day!
