synchronous USART

Hi everyone.
I need to build a system based at STM32F4xx that use absolute encoder with BiSS protocol (http://www.biss-interface.com). This protocol is based at synchronous RS485. I have HW that convert differential signals to single ended.

There is an option to use USART in synchronous mode. I couldn't find where SCLK pin is placed. I guest that USARTx_CK is usart clock, but I'm not sure.

In general what do you suggest:
1. To use synchronous USART.
2. To SPI MISO &SCK.

Any way, in both configuration I'll need to make some bit shift operation to recognize the data.

Thanks in advance.
