Hi,
    I have several time strict  TIMER ISR and I tested the execution time of one of them.The result is that 47 instructions(indluding 3 branch instructions) costs 3 us.My chip is stm32f103 and all code and data is placed at internal flash ram.Can anyone tell me is that a normal case and whether the time can be reduced or not?

Thank you in advance!
