STM32F103C8T6 enables SPI1, but does not use MISO pin (PA6), can this pin reuse other functions? For example, timer function.

Hello @112233

If you are using the SPI1 without MISO (PA6) (in Half-Duplex Master), you can configure the PA6 on any of the modes mentioned on the screenshot:

The PWM output of the timer channel is reused. After SPI is enabled, the PWM output is not displayed.

Hello,How to configure CR register?

What I suggest you is to generate your project using CubeMX (peripherals and pinout initialization and configurations). Then, do the codding part.

It still doesn't work. Is it a BUG inside the chip?
