No Output SPI Clock Pin

For my design, I'm utilizing an STM32F103CBT7 with HAL functionalities and a 72MHz system clock.
SPI 1 is set to Master, with a 16-bit data width and a data rate of 18 MBits/s.
There is a data bit on the MOSI pin when sending data out, but no Clock pulse on the SCK pin.
I'm stumped as to what's wrong.
Is there anything you could suggest?
I've read some tutorials like ... tures.html, but I still have no idea.
