With nRF51822, which pins are assigned to SPIS?

With nRF51822, which pins are assigned to SPIS?https://devzone.nordicsemi.com/f/nordic-q-a/9554/with-nrf51822-which-pins-are-assigned-to-spisI've read the document, 51822 Product Specification 3.1 But I can't find which pins are assigned for SPIS. I'm using QFN type. Directly speaking, can I achieve SPIS and UART functions with Seeed Micro module?

You can assign SPIS and UART to any pin.</p><div style="clear:both;"></div>
