Summary
The clock configuration, timers, and I/O lines are the general-purpose peripherals shown in this chapter, commonly supported by a wide range of microcontrollers. Although implementation details such as register names and placement may differ on other targets, the proposed approach is valid on most embedded platforms, and the general-purpose peripherals are the bricks for building the most basic system functionalities as well as providing a means of interaction with sensors and actuators.
In the next chapter, we will focus on serial communication channels provided by most microprocessors as communication interfaces toward other devices, and peripherals in the proximity of the target system.
