ADC takes over function of every ADC pin when enabled?

When I enable the ADC on my STM8A6266 MCU every PIN which is a ADC channel is blocked by the ADC? 

For example:

PIN1-PIN8 are ADC channels 1-8, I enable the ADC and doing conversions on ADC channel 1 then I can't use PIN2 (ADC_channel 2) for EXTI interrupt? Tried it several times also with polling but it seems when the ADC is enabled it takes over the function of every PIN which is associated with the ADC. So even reading  input GPIO value isn't possible when ADC enabled.

 

Couldn't find any comment regarding this in the datasheet or reference manual.
