9.3.4: What is not measured?

The times presented in this document are not intended to represent best or worst case times, nor are all directives included. For example, no times are provided for the initialize executive and fatal_error_occurred directives. Other than the exceptions detailed in the Determinancy section, all directives will execute in the fixed length of time given.

Other than entering and exiting an interrupt service routine, all directives were executed from tasks and not from interrupt service routines. Directives invoked from ISRs, when allowable, will execute in slightly less time than when invoked from a task because rescheduling is delayed until the interrupt exits.
