Selecting GPIO in shared pins for STM32G030F6

In pins that share more than one GPIO, how do you set the GPIO to connect to the physical pin?For instance, for pins PA12/PA10 and PA11/PA9 one can remap them using SYSCFG_CFGR1 register. But is unclear for the rest of the pins. For example, TSSOP20 ...

How to set Adc for maximum rate

I have design  pcb for Stm32H723VGT6 ( 100 pins  TQFP )  my job is read adc 12 bit and transfer over usb to PC  . i have set sysclk to 550 MHz and ADC clock to 64 MHz  so i got sample rate to 1.3 Msps but mcu are hot. So i have sysclk to 400 and ADC ...
