interrupt request

There are therefore only 15 interrupt request lines available for hardware.

This event is called trigger and causes an interrupt request.

An interrupting module asserts one of the interrupt request lines.

They are often used to control interrupt requests by acting on the highest priority request.

When working with personal computer hardware, installing and removing devices, the system relies on interrupt requests.

The criteria used to prioritize interrupt request levels are determined by the operating system, which is programmed to give higher priority to more important devices.

Also, interrupt requests will have been disabled by executing or , requiring that the operating system re-enable them.

When the computer is first turned on, compatible devices are identified and assigned non-conflicting addresses and interrupt request numbers.

Interrupt Request Register, a register used for managing interrupts in programmable interrupt controllers.

The problem involves something the Interrupt Request (IRQ) lines, represented as a number from 0 to 15.

The act of initiating a hardware interrupt is referred to as an interrupt request (IRQ).

The serial port is an 8250 or a derivative (such as the 16450 or 16550), mapped to eight consecutive IO addresses and one interrupt request line.

Interrupt request (IRQ)

When an interrupt handling module recognizes an interrupt request at a priority it handles, it arbitrates for the bus in the usual fashion described above.

On most 68000 family based Macintosh computers, an interrupt request can also be sent by holding down the command key and striking the power key on the keyboard.

The interrupt request lines (IRQ1 - IRQ7) prioritize interrupts.

Priority encoders establish the priority of competing inputs (such as interrupt requests) by outputting a binary code representing the highest-priority active input.

The interrupt priority level (IPL) is a part of the current system interrupt state, which indicates the interrupt requests that will currently be accepted.

However, some architectures permit a greater range of values, where each value enables interrupt requests that specify a higher level, while blocking ones from the same or lower level.

A straightforward method of implementing a network driver is to interrupt the kernel by issuing an interrupt request (IRQ) for each and every incoming packet.

External interrupts are triggered by falling/rising edges or high/low potential at the interrupt port, leading to an interrupt request (IRQ) in the controller.

The interrupt request level (IRQL) is the priority of an interrupt request.

Speech playback on the Atari normally disabled interrupt requests and shut down the ANTIC chip during vocal output.

If the caps lock LED sticks on or off, the CPU is not servicing CIA interrupt requests.

If a debugger is installed on the machine, it is activated when the interrupt request is processed, allowing the user to view and usually modify the computer's internal memory.
