Is it possible to change GPIO_Mode and GPIO PU/PD settings from Device configuration tool on STM32G0?

[GCaso.2]

When I assign a pin to a peripheral (e.g. comparator 3) the corresponding GPIO mode is fixed to Analog and cannot be changed. As a consequence, no pull-up or pull-down resistor can be inserted. By changing System.ioc with a text editor the correct code is generated and the device behaves as expected (pull-up register inserted)

PE7.GPIOParameters=GPIO_Label

changed to

PE7.GPIOParameters=GPIO_PuPd,GPIO_Label,GPIO_Mode

Added rows:

PE7.GPIO_Mode=GPIO_MODE_AF_OD

PE7.GPIO_PuPd=GPIO_PULLUP

The easier way to set pull-up or pull-down GPIO resistor is through direct register control in code:

GPIOE->PUPDR = (0x1 << (0x2U * 0x7));

where GPIOE is used GPIO port

           0x1 is for pull-up resistor (0x0 - no pull-up no pull-down, 0x2 pull-down)

           0x7 is the number of GPIO pin
