To configure McSPI on Beagle Bone

Hello All,
I am in the process of configuring the McSPI in a program to run on the Beagle Bone.I didnt get any starterware examples which uses SPI. So by using the available wrapper functions for SPI,I am using SPI1_SCLK and SPI1_ D0 in master mode Transmit only mode.
1.Since I am using SP1, my chNum parameter in McSPIMasterModeConfig function must be 1 right??
2.What should be the pinMode parameter in the same function?The bits IS DPE1 DPE0 & TRM are 0 1 0 10 respectively-so then what will be my pinMode.

Regards
Savitha
