ID82C86H

The ID82C86H is an integrated circuit (IC) component that serves as an advanced general-purpose programmable interrupt controller. It provides flexible interrupt processing capabilities to enhance the performance and efficiency of computer systems. Here are the key features and functionalities of the ID82C86H: 1. Interrupt Controller: The ID82C86H acts as a programmable interrupt controller, managing and prioritizing interrupts from various devices in a computer system. It supports up to 16 interrupt request (IRQ) lines. 2. Programmability: This IC component allows software programming of interrupt priorities. It enables the system designer to allocate different priority levels to different devices and tailor the interrupt servicing flow based on system requirements. 3. Interrupt Management: The ID82C86H provides versatile interrupt management, including masking, unmasking, and interrupt acknowledgement functions. It allows masking of individual interrupts to prevent them from being serviced, thereby ensuring proper handling of different system events. 4. Cascading Capabilities: The ID82C86H can be cascaded with other interrupt controllers, such as the Intel 8259, to increase the interrupt vector space and accommodate a larger number of devices that require interrupt servicing. 5. Priority Rotation: This IC component incorporates priority rotation logic that offers fair servicing of interrupts across multiple devices. It helps prevent starvation of lower-priority interrupts, ensuring timely processing of all pending interrupts
