6 Detailed Description
6.1 Overview
The Texas Instruments MSP430FR59xx family of ultra-low-power microcontrollers consists of several
devices featuring different sets of peripherals. The architecture, combined with seven low-power modes is
optimized to achieve extended battery life for example in portable measurement applications. The devices
features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to
maximum code efficiency.
The MSP430FR59xx devices are microcontroller configurations with up to five 16-bit timers, Comparator,
universal serial communication interfaces (eUSCI) supporting UART, SPI, and I2C, hardware multiplier,
AES accelerator, DMA, real-time clock module with alarm capabilities, up to 40 I/O pins, and an high-
performance 12-bit analog-to-digital converter (ADC).
6.2 CPU
The MSP430 CPU has a 16-bit RISC architecture that is highly transparent to the application. All
operations, other than program-flow instructions, are performed as register operations in conjunction with
seven addressing modes for source operand and four addressing modes for destination operand.
The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to-
register operation execution time is one cycle of the CPU clock.
Four of the registers, R0 to R3, are dedicated as program counter, stack pointer, status register, and
constant generator, respectively. The remaining registers are general-purpose registers.
Peripherals are connected to the CPU using data, address, and control buses, and can be handled with all
instructions.
The instruction set consists of the original 51 instructions with three formats and seven address modes
and additional instructions for the expanded address range. Each instruction can operate on word and
byte data.
