If i design my USB circuit to use soft_connect using USB_CONNECT, does that mean I cannot use any SSP devices in my design? As the USB_CONNECT is the same line as SCK?

No. SCK can be switched to different Pins via IOCON. You can also use PIO2_11 or PIO0_10. Since PIO0_10 is used for Debugging (SWD) I would suggest to use PIO2_11.
In 'IOCON SCK location register' (IOCON_SCKLOC) this Pin has to be selected also as SCK output.

Hello cksa361,

see User Manual UM10375 and search for "SCK" and all the locations are shown. First mark pins which are used and at the end choose for pins (SCK) which are left open and connected to the pin on the board.
