How to Enable clock for SYCFG in STM32WB55?

Hi

I am new here using STM32WB55. I am writing drivers and API for GPIO and interrupt. But I'm facing some difficulty to find the pin for SYCFG to enable clock in APB2ENR. SYCFG is connected to the APB2 bus and when I use APB2ENR to enable SYCFG clock but in reference manual there is no pin declared for to enable SYCFG clock . Can you help me how to enable clock for system configuration. Thank ​

Hi,

as far as I know the clock to the SYSCFG is always on. Since this is such an essential module it makes no sense to make its clock gated.

So do you have any issues with SYSCFG not being operational?

Regards

Thomas
