    Are you saying to want to cause a 100ms delay? Assuming you are using C2000Ware (or controlSUITE) you could use the DELAY_US() macro in

    \device_support\f2833x\common\include\DSP2833x_Examples.h

    You'll want to make sure that you use the value of CPU_RATE that corresponds to 100MHz though (default is 150MHz). The macro is in terms of microseconds, so for 100ms you'll need to pass it 100000.

    Or are you trying to create the delay in some other way?
