WebSoftware Interrupt (SWI) functions are functions that run in Supervisor Mode of ARM7™ and ARM9™ core and are interrupt protected. SWI functions can accept arguments and can return values. They are used in the same way as other functions. The difference is hidden to the user and is handled by the C-compiler. It generates different code instructions to call … WebAn interrupt service routine (ISR) is a software routine that hardware invokes in response to an interrupt. ISR examines an interrupt and determines how to handle it executes the handling, and then returns a logical interrupt value. If no further handling is required the ISR notifies the kernel with a return value.

WebSoftware Interrupts The INT instruction executes a software interrupt. The code that handles the interrupt is called an interrupt handler. Syntax: INT number (number = 0..FFh) The Interrupt Vector Table (IVT) holds a 32-bit segment-offset address for each possible interrupt handler. Interrupt Service Routine (ISR) is another name for interrupt WebSoftware interrupts are triggered by the instruction int. For example, the instruction "int 14h" triggers interrupt 0x14. The processor then stops the current program, and jumps to the code to handle interrupt 14.
