Many engineers have found that their applications require more external interrupt requests than are provided on the Intel 186 family of embedded processors. Intel P82C59A-2 programmable interrupt controllers (PIC) can be added to a design to increase the number of available interrupt requests; this application note explains how.
This application note contains the following:
- A reference design
- An analysis of the timings for the reference design and design considerations related to this timing data
- Design considerations for cascading 82C59As
- Source code for the programs used to test the reference design and design considerations
