SLAU144†The MSP430F241x devices are identical to the MSP430F261xdevices, with the exception that the DAC12 modules and the DMAcontroller are not implemented.descriptionThe Texas Instruments MSP430 family of ultralow-power microcontrollers consists of several devices featuringdifferent sets of peripherals targeted for various applications. The architecture, combined with five low-powermodes is optimized to achieve extended battery life in portable measurement applications. The device featuresa powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum codeefficiency. The calibrated digitally controlled oscillator (DCO) allows wake-up
