This application report describes the implementation of a real-time (RTC) on the MSP430 using either Timer_A or the Watchdog Timer. The MSP430 family of microcontrollers from Texas Instruments, is a family of ultralow-power, 16-bit RISC microcontrollers with an advanced architecture and a rich peripheral set. The report gives a general overview of the MSP430 family, and discusses the real-time clock application in detail. It gives a detail circuit diagram, two code examples, and a general discussion on accuracy and implementation issues.
