The 8254 is a programmable interval timer/counter designed for use with Intel microcomputer systems. PIC: Hey, CPU, I have an interrupt for you! (a bit later) CPU: Yeah, which vector? PIC: Lemme see, uh, vector 39! Because it's not atomic, someone can make the interrupt non-deliverable in the meantime. For example, mask it or, in the Local APIC's case, raise TPR to a higher priority. I think, with the 8259, lowering a† Microchip products meet the specification cont ained in their particular Microchip Data Sheet. † Microchip believes that its family of products is one of the mo st secure families of its kind on the market today, when used i n the intended manner and under normal conditions.

The only way to change the vector offsets used by the 8259 PIC is to re-initialize it, which explains why the code is "so long" and plenty of things that have apparently no reasons to be here.2 Datasheet, Volume 1 of 2.

This coaxial cable is perhaps the most common, basic and easy-to-understand cables.I still feel that IBM's design of the PC, especially with regard to the PIC, is just awful. Had IBM followed the 8259 datasheet and liberally used an 8259 on the mainboard as a master and cascaded say two slave 8259's for the mainboard interrupts and two slave 8259's for the ISA bus things would have been very different.
