Alternate pin for I2C1_SCL on STM32C011J6Mx SO8N

[stevecimo]

Hi ALL

I'm playing with a STM32C011J6Mx on  a plane breakout board.

Sorry if this a basic question, new to using the SMT32 , last time I played with MCUs was 6809 CPU :)

I wanted to use I2C and SWD, to use both I need to move the I2C1_SCL to it's alternate pin, when I CTL+ left click on the  PC15 (I2C1_SCL) it shows PA8 has an alternative.

But when I select PA8 , I2C_SCL , is not listed has an alternative function.

But the data sheet show it has a Alternate function on PA9, 

How do I activate PA9, in the MX tool?

 

Regards, Stephen
