Chapter 9, Exercise 4

Do the i.MX RT1060 processors support the concept of supervisor mode instruction execution? Explain your answer.

Answer

Performing a search for supervisor in the i.MX RT1060 processor reference manual produces a few hits. However, all of these usages refer to access restrictions related to a particular subsystem, such as the FLEXCAN module.

Supervisor mode in the i.MX RT1060 processor does not operate at the instruction execution level, so these processors do not implement supervisor mode instruction execution as described in Chapter 9.
