1us delay function

Best way is use RTI and code like this:

{
U32 waitTill = currentRTIvalue + wtime;
while((I32)(currentRTIvalue - waitTill) < 0) // trick to compare over RTI overload
{ /* do nothing */ }
}


replace "currentRTIvalue" to used RTI counter

Advantage: it not have problem with injected interrupt

Disadvantage 1: you need program RTI to higher freqency than wait time inverted value

Disadvantage 2: It is effective only for small delays (less then ~20-40us). For longer delays is better use RTOS and use this time for another task.
