RS 03:49 PM PCB Development: Munti-function OMAP pins

Hello,
I would like to use the SPI1 on the OMAP with two separate devices are the pin functions in the critical link datasheet table 1 exhaustive?
For instance, could I use pin 61 as SPI1_SCS[5]? The OMAP documentation has it liste... Rachel Shaska
