Title:
Vectored Interrupt Controller on 8-Bit PIC Microcontrollers

Description:
This technical brief will cover the Vectored Interrupt Controller on 8-bit PIC® devices. Traditionally multiple interrupt routines are needed to handle interrupts coming from different sources. Through this vectored interrupt controller, the multitude of interrupt requests signals previously mentioned can be reduced to a single interrupt request signal to the CPU. This is implemented through the use of an Interrupt Vector Table which organizes interrupts based on the natural priority of interrupts and user defined priorities. This technical brief will describe the vectored interrupt controller in further detail.
