Hello, I try to understand interrupt priorities in STM32F0. In RM0091 there is table 36. In the second column, I can see priority values from 7 to 38. What are these values? How to set them in CubeIde?

 As far as I know, this MCU has only 4 levels (2bits). In CubeIde I can set only values 0,1,2,3. And the second question: if I set all levels to 0, in what priority interrupts will be served (according to table index?).
