Watchdog Timer and Low Power

In the embedded systems domain, achieving an optimal balance between operational reliability and power efficiency is paramount. This chapter delves into two pivotal technologies that stand at the forefront of this balance: the watchdog timer and low-power modes. Both elements are instrumental in creating systems that not only conserve energy but also maintain robust performance and reliability over time. This chapter aims to explore the intricacies of implementing watchdog timers and leveraging low-power modes within PIC microcontrollers. By understanding these concepts, developers can design systems that not only optimize energy usage but also enhance reliability and longevity. Through practical examples and theoretical insights, we will uncover the strategies to harness these technologies effectively, paving the way for the creation of sophisticated, energy-conscious, and dependable embedded systems.
