      [STM103CBT6] interrupt ExtIx versus frequency APB2

I have a problem with the simultaneous handling of interrupts EXTIx ORAX converter ADC1. I must probe the A / C with a maximum frequency. Therefore, I need to set the maximum possible frequency of the bus APB2. As we increase the frequency of bus APB2 above 4.5 MHz to stop working interrupt eXTix, A/C works. What's wrong? I generate code from STM32CubeMX.
