Detailed Description
Type of a Time Measurement object.
- Note
- The maximum measurable time period depends on the implementation of the realtime counter and its clock frequency.
- The measurement is not 100% cycle-accurate, it can be in excess of few cycles depending on the compiler and target architecture.
- Interrupts can affect measurement if the measurement is performed with interrupts enabled.
