CC2640R2F: Precise us/ms delay without Timer Counter.

Part Number: CC2640R2F

Dear all,

I don't find any some us/ms delay in driverlib. 

I have used TIVA C M4 core, in driverlib, we have SysCtlDelay(cnt) to do delay.

Does CC2640R2F also can do this function without using Timer Counter.

Many thanks for your help.
