What is Lecu2 4 about?

The ARM architecture features seven operating modes, including six privileged modes (such as Abort, Fast Interrupt, and Supervisor) and one non-privileged User mode. Each mode has specific functions and access levels, allowing for efficient exception handling and interrupt management. Exceptions are events that temporarily halt normal execution, with dedicated handlers for various types, including reset, software interrupts, and data aborts, all managed through a vector table for quick access.
