The entire page could use some editing. As the above comment says, no PC ever used an Intel 8259 if Intel's 8259A datasheet is to be believed; it had to be an 8259A. (And wasn't the original PC introduced in 1981 anyway?) Further, many people appear to be confused about the difference between the IBM PC and XT.PROGRAMMABLE INTERRUPT CONTROLLER, 8259A datasheet, 8259A circuit, 8259A data sheet : INTEL, alldatasheet, datasheet, Datasheet search site for Electronic Components ... 8259A Programmable Interrupt Controller.

An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for curren t devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revisi on of silicon and revision of document to which it applies.

Jan 11, 2020 · INTEL 8259 DATASHEET PDF - The Intel is a Programmable Interrupt Controller (PIC) designed for the Intel and Intel microprocessors. The initial part was , a later A suffix. Looking in the PIC's datasheet, I noticed two things: The pins AN0 to AN5, the ones mis-reporting non-zero values, are also CNx pins. These pins are "Change Notification" pins, that are meant to raise an interrupt when the value on the pins changes. There is a "weak pull-up" that can be enabled on all CNx pins.The D8259 is a soft Core of Programmable Interrupt Controller. It is fully compatible with the 82C59A device. Our efficient IP core can manage up to 8-vectored priority interrupts for the ...8259 PIC (Programmable Interrupt Controller) The 8259 chip is the "heart" of the whole process of doing hardware interrupts. External devices are directly connected to this chip, or in the case of the PC-AT compatibles (most likely what you are most familiar with for a modern PC) it will have two of these devices that are connected together.8255A - Programmable Peripheral Interface - The 8255A is a general purpose programmable I/O device designed to transfer the data from I/O to interrupt I/O under certain conditions as required.
