A hardware interrupt is a condition related to the state of the hardware that may be signaled by an external hardware device, e.g., an interrupt request (IRQ) line on a PC, or detected by devices embedded in processor logic (e.g., the CPU timer in IBM System/370), to communicate that the device needs attention from the operating system (OS) [7] or, if there is no OS, from the bare metal ...
The 8259 may be configured to work with an 8080/8085 or an 8086/8088. On the 8086/8088, the interrupt controller will provide an interrupt number on the data bus when an interrupt occurs. The interrupt cycle of the 8080/8085 will issue three bytes on the data bus (corresponding to a CALL instruction in the 8080/8085 instruction set).
In computing, a spurious wakeup occurs when a thread wakes up from waiting on a condition variable and finds that the condition is still unsatisfied. It is referred ...

INT is an x86 instruction that triggers a software interrupt, and 13 hex is the interrupt number (as a hexadecimal value) being called. Modern computers come with both BIOS INT 13h and UEFI functionality that provides the same services and more, with the exception of UEFI Class 3 that completely removes CSM thus lacks INT 13h and other interrupts.
The letter C in the 26C92 part number has nothing to do with the fabrication process; all NXP UARTs are CMOS devices. The 28L92 is an upwardly compatible version of the 26C92, featuring selectable 8- or 16-byte transmitter and receiver FIFOs, improved support for extended data rates, and faster bus timing characteristics, making the device more ...
