说明：  MSP430 系列是一个 16 位的、具有精简指令集的、超低功耗的混合型单片机，在 1996 年问世，由于它具有极低的功耗、丰富的片内外设和方便灵活的开发手段，已成为众多单片机系列中一颗耀眼的新星。回忆 MSP430 系列单片机的发展过程，可以看出有这样三个阶段：
(MSP430 series is a 16-bit, with a reduced instruction set, and ultra low power single chip hybrid, in 1996, come out, because it has very low power, rich on-chip peripherals and development of convenient and flexible means has been a large number of microcontrollers in a dazzling star. MSP430 MCU memory development process, we can see that there is such three phases:)
