TRAP interrupt is ________________.
TRAP interrupt is ________________.
Open in App
Solution
The correct option is B not maskable
TRAP interrupt is not maskable.
TRAPis non-maskable
interrupt. Masking is preventing the interrupt from disturbing the main program. All
the hardware interrupts, except TRAP are
disabled, when the processor is resettled.
A non-maskable
interrupt is a hardware interrupt that standard interrupt-masking techniques in the system cannot ignore. It typically occurs to
signal attention for non-recoverable hardware errors.
A TRAP is typically a type of synchronous interrupt typically caused by an exceptional
condition. A trap usually results in a switch to kernel mode, wherein the
operating system performs some action before returning control to the
originating process.
