How to change SPI0 pins on MQX 4.1 for a TWRK64

I've been using a K64 Tower Board with CW 10.6 and MQX 4.1.  Please bare with me as I try to explain what I'm trying to accomplish.


1.  The MQX 4.1 SPI driver has    "SPI0_SIN" on PTD3   /     "SPI0_SOUT" on PTD2      /  "SPI0_SCK" on PTD1   , (I have verified this stuff with a scope using a provided example project)

2.  According to the data sheet of the K64, SPI0_SIN/SPI0_SOUT/SPI0_SCK   can be "routed" to different pins, for example SPI0_SIN can also be "routed" to PTA17, PTC7 (in addition to PTD3 (which is the default)) 

3.  MY QUESTION IS:     How can I change the default "pin mapping" ?  For example how can I make SPI0_SIN be "routed" to PTA17 as opposed to PTD3 ?


Thank you for your time and help in advance,
