This chapter discusses interrupts, which are of critical importance when implementing efficient input/output operations for microcontroller applications. Topics include interrupt fundamentals, PIC24 μC interrupt sources, and an introduction to using interrupts for accomplishing I/O. A first look at the powerful timer subsystem of the PIC24 μC uses a timer as a periodic interrupt source.
After reading this chapter, you will be able to:
Discuss the general function of interrupts within a microprocessor and interrupt implementation on the PIC24 μC.
Describe the difference between ...
