A modern-day CPU enables code to be performed in various processor mode, which supply various benefits for accessing the system. By contrast, the operating system runs in manager mode, which enables direct interaction with gadgets and allows access to all memory addresses.
The CPU does not understand this difference in between routine programs and the operating system; all it understands is the existing mode, which it understands from the worth of a register (which for the ARM is a surprise register called CPSR).

In any gadget that has an os, there’s generally a method to make modifications to how the gadget works. This is far from a delighted mishap; among the factors operating systems are constructed of portable code instead of irreversible physical circuits is so that they can be altered or customized without needing to ditch the entire gadget.
