STM32F100/103/303 AP_Perph

Hi all.
I look for all info about the peripheral co-processor: pin definition in the code, pin layout …
Thank for all for your help, I will glad to get any recommendation / explanation.

All the info you need is there

Thank you.
I have checked this library –
I am looking hwdef for IOMCU STM32F100/103/303 --version for 8 AUX outputs, but I miss this point.
We have ADSB,GPS,HWESC… but no one has definition for GPIO for AUX.
