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.
