NOP Vs _nop_()?

In one of my project I am talking with MX909 Driver IC with C51 ucontroller. To initialize MX909 if I write module in Assembly language it's working fine. Once I replaced with C same module it's not working.

The only difference I can make for both assembly and C languages is NOP and _nop_() instruction. Is both instructions will take same number of machine cycles?

Thanks,

  • you're suffering from a fallacy.

    Hmmm ... It's sounding like you're a member of the Erik luv-fest brigade!

    I'm not going to bother responding to your individual points because - Well, what's the point!?

    But, by the way, I am not the original poster, I am not "Jack Sprat" and I am not even the alter ego of "Christoph Franck".

    I would expect professionals to be a bit more professional. Experience is not directly proportional to superiority!
