I have a question here about timing. No that I have any problema but I want to know if there are any tolerances you have to take into account when your application rely heavily timing .
With the GP timer0 I have a period of 10 microseconds , and the application which I am working on counts the number of timer0 interrupts between events in order to calculate the frequency of the events.
My question is how accurate is the GP timer0 in the following case : core clock 500 MHz and peripheral clock 100 MHz on the BF538 evaluation board ?
Do I have for example a rock steady 10.000000 microseconds period ?? Or are any for example temperature drifts etc. ??
Further the same question for the onboard RTC, because I use this for time stamps.
