Interrupts

Examples of the interrupts:

  •   I/O device request, OS call, page fault
  •   power failing, arithmetic overflow
  •   Invalid opcode, breakpoint, protection violation

Interrupts (aka faults, exceptions, traps) frequently require

  •   connecting return address
  •   surprise jump (to vectored address)
  •   state change ( for example, to kernel mode)
  •   saving of PSW (including CCs)
