partially solved issue with random modulator and ADC clock stopping at the end of ЛЧМ. Done: when we want to stop clocks -- enable IRQ on sloewr clock (TIM11). In IRQ switches TIM4, TIM11 to one-pulse mode, disables IRQ. When we starting these timers th next time -- we resets their counters, one-pulse mode disables.
