how to generate 200nS delay using AT89S52 ic

I am doing ADC interfacing using AT89S52 IC and i need 200ns delay for one of my control signals. if it is possible then can you please suggest me the assembly code to generate 200ns delay...

  • Yes; nop is one way to generate a delay.
    How long that delay is depends on your chip - its clock settings and other factors (not being a C51 guy I cannot explain in detail; ARM7s have flash acceleration units etc. that also influence performance) and the efficiency of the code used. The best thing for you to do it to measure with a scope.
