Overview of MSP430 Timers
Overview of MSP430 Timers
The MSP430F5529 timers are highlighted in the following block diagram.
• Yellow marks the three instances of the TIMER_A module.
• Pink was used for TIMER_B.
• Dark brown highlights the real-time clock (RTC_A).
• Light brown differentiates the Watchdog timer inside the SYS block
The “Timers in Training” callout box describes where the various timers are discussed in this
workshop. Timers A and B are covered in this chapter. We have already covered the Watchdog
timer in a previous chapter.
The RTC module will be discussed in a future chapter. A brief description of the RTC tells us that
it’s a very low-power clock; has built-in calendar functions; and often includes “alarms” that can
interrupt the CPU. It is frequently used for keeping a time-base while the CPU is in low-power
mode.
