1.1 Exceptions Overview ARM v7 Core supports multiple great features for handling exceptions and interrupts. Which includes the Nested Vectored Interrupt Controller (NVIC). Micro-Coded Architecture So that interrupt stacking, entry, and exit are done automatically in hardware. Which offloads this work overhead … See more When an interrupt (exception) is fired, the main (foreground) code context is saved (pushed) to the stack and the processor branches to the … See more The ARM core can detect a higher priority exception while in the “exception entry phase” (stacking caller registers & fetching the ISR routine … See more The first entry in the table (lowest address) contains the initial MSP. All other addresses contain the vectors (addresses) to the start of … See more The pre-emption happens when a task is abandoned (gets interrupted) in order to handle an exception.

WebCPU is a busy taskmaster. Any subsystem requiring the attention of the CPU generates Interrupt. INTERRUPT (INT) is both a control and status signal to the CPU. Generally, the memory subsystem does not generate Interrupt. The Interruption alters the CPU execution flow. Recognising and servicing Interrupts is fundamental to any processor design. WebA hardware interrupt is a signal that stops the current program forcing it to execute another program immediately. The interrupt does this without waiting for the current program to finish. It is unconditional and immediate which is why it is called an interrupt - it interrupts the current action of the processor. kymco user manual

The Interrupt Flow is a connection used to define the two UML concepts of connectors for Exception Handler and Interruptible Activity Region. An Interrupt Flow is a type of activity edge.
