TMS570LC4357: 4357

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

Hi ,

        We are using 570LC4357 micro controller for our project . We are using RTI in our application to give 1 micro sec timer interrupt , Basically we are using this for sampling of AC signal . Here are facing an issue where RTI is generating interrupt at every 0.96 micro sec instead of 1 micro sec and measuring is done through scope. Can any one tell me the reason for this behavior as it is not desirable in our project .

  • Hello,

    Normally the RTI clock is 75MHz (HAlCoGen generated code). If the counter frequency is 9.375MHz (UC compare = 7), you can get 1ms interrupt by placing 9375 to compare 0 and update compare 0 registers.

    What is you RTI configuration?
