output the CLK on an external mcu pin

[mariuszoll]

Hi,

I use on my project a STM8S207K8 mcu from ST, I configured the internal oscillator, HSI to work at 16Mhz. I use IAR embedded workbench.
I want to output the CLK signal on an external CCO pin.
Could you help me please how to do it? Since now I haven't work with STM8S mcus.

Thank you in advance.

and the STM8S Reference Manual

Page no. 47 says something about remapping alternate function. AFR2. Where can I find detailed datasheet which provides details about the registers?

I prefer to use the Reference Manual.

I am reading the reference manual. I will see if I can find a solution.

I found that I have to set the OPT bit from the FLASH_CR2 register in order to have access to option bytes, but how to set AFR2, I haven't found yet.
