Delay tiva problem

Hello guys, i have a problem, and I have no idea what happening... I'm trying to make a delay of only a few microseconds, for example, 10us. For this, I'm using a Wait function, and a timer, where I set this timer with Period = 8, that is, Period = Clock / freqtimer. But the peripheral enable is entering an infinite looping, when I do the step by step, it simply locks on line 86.
