Abstract
This chapter introduces the concept of a timer to independently track and/or trigger events based on the time elapsed [1–3]. A timer uses an independent, free-running, binary counter to track the passage of time. Timers are a peripheral to the CPU, which allows the CPU to handle other tasks while the timer runs separately. Timers can trigger interrupts that are then serviced by the CPU through routines. This chapter presents the concept of a timer and then looks at the details of the timers available on the MSP430FR2355 MCU.
