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.

6.3 Operating Modes

The MSP430 has one active mode and seven software-selectable low-power modes of operation. An interrupt event can wake up the device from low-power modes LPM0 through LPM4, service the request, and restore back to the low-power mode on return from the interrupt program. Low-power modes LPM3.5 and LPM4.5 disable the core supply to minimize power consumption.

The following eight operating modes can be configured by software:

  • Active mode (AM)
    • All clocks are active
  • Low-power mode 0 (LPM0)
    • CPU is disabled
    • ACLK active
    • MCLK disabled
    • SMCLK optionally active
    • Complete data retention
  • Low-power mode 1 (LPM1)
    • CPU is disabled
    • ACLK active
    • MCLK disabled
    • SMCLK optionally active
    • DCO disabled
    • Complete data retention
  • Low-power mode 2 (LPM2)
    • CPU is disabled
    • ACLK active
    • MCLK disabled
    • SMCLK optionally active
    • DCO disabled
    • Complete data retention
  • Low-power mode 3 (LPM3)
    • CPU is disabled
    • ACLK active
    • MCLK and SMCLK disabled
    • DCO disabled
    • Complete data retention
  • Low-power mode 4 (LPM4)
    • CPU is disabled
    • ACLK, MCLK, SMCLK disabled
    • Complete data retention
  • Low-power mode 3.5 (LPM3.5)
    • RTC operation
    • Internal regulator disabled
    • No data retention
    • I/O pad state retention
    • Wake-up input from RST, general-purpose I/O, RTC events
  • Low-power mode 4.5 (LPM4.5)
    • Internal regulator disabled
    • No data retention
    • I/O pad state retention
    • Wake-up input from RST and general-purpose I/O

6.4 Interrupt Vector Addresses

The interrupt vectors and the power-up start address are in the address range 0FFFFh to 0FF80h (see Table 6-1). The vector contains the 16-bit address of the appropriate interrupt-handler instruction sequence.

(1) Multiple source flags
(2) Interrupt flags are located in the module.
(3) A reset is generated if the CPU tries to fetch instructions from within peripheral space or vacant memory space.
(Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable cannot disable it.
(4) Reserved interrupt vectors at addresses are not used in this device and can be used for regular program code if necessary. To maintain compatibility with other devices, it is recommended to reserve these locations.
(5) Only on devices with ADC, otherwise reserved.

6.6 Bootloader (BSL)

The BSL enables users to program the FRAM or RAM using a UART serial interface. Access to the device memory by the BSL is protected by an user-defined password. Use of the BSL requires four pins (see Table 6-3). BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK pins. For complete description of the features of the BSL and its implementation, see the MSP430 Programming With the Bootloader User's Guide.

6.7 JTAG Operation

6.7.1 JTAG Standard Interface

The MSP430 family supports the standard JTAG interface, which requires four signals for sending and receiving data. The JTAG signals are shared with general-purpose I/O. The TEST/SBWTCK pin is used to enable the JTAG signals. In addition to these signals, the RST/NMI/SBWTDIO is required to interface with MSP430 development tools and device programmers. Table 6-4 lists the JTAG pin requirements. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide. For a complete description of the features of the JTAG interface and its implementation, see MSP430 Programming Via the JTAG Interface.

6.7.2 Spy-Bi-Wire Interface

In addition to the standard JTAG interface, the MSP430 family supports the 2-wire Spy-Bi-Wire interface. Spy-Bi-Wire can be used to interface with MSP430 development tools and device programmers. Table 6-5 lists the Spy-Bi-Wire interface pin requirements. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide. For a complete description of the features of the JTAG interface and its implementation, see MSP430 Programming Via the JTAG Interface.

6.8 FRAM

The FRAM can be programmed through the JTAG port, Spy-Bi-Wire (SBW), the BSL, or in-system by the CPU. Features of the FRAM include:

  • Low-power ultra-fast write nonvolatile memory
  • Byte and word access capability
  • Programmable and automated wait state generation
  • Error correction coding (ECC) with single bit detection and correction, double bit detection

For important software design information regarding FRAM including but not limited to partitioning the memory layout according to application-specific code, constant, and data space requirements, the use of FRAM to optimize application energy consumption, and the use of the memory protection unit (MPU) to maximize application robustness by protecting the program code against unintended write accesses, see MSP430™ FRAM Technology – How To and Best Practices.

6.9 Memory Protection Unit (MPU)

The FRAM can be protected from inadvertent CPU execution or write access by the MPU. Features of the MPU include:

  • Main memory partitioning programmable up to three segments
  • Access rights for each segment (main and information memory) can be individually selected
  • Access violation flags with interrupt capability for easy servicing of access violations

6.10 Peripherals

Peripherals are connected to the CPU through data, address, and control buses. Peripherals can be managed using all instructions. For complete module descriptions, see the MSP430FR57xx Family User's Guide.

6.10.1 Digital I/O

Up to four 8-bit I/O ports are implemented:

  • All individual I/O bits are independently programmable.
  • Any combination of input, output, and interrupt conditions is possible.
  • Programmable pullup or pulldown on all ports.
  • Edge-selectable interrupt and LPM3.5 and LPM4.5 wake-up input capability is available for all ports.
  • Read and write access to port-control registers is supported by all instructions.
  • Ports can be accessed byte-wise or word-wise in pairs.

6.10.2 Oscillator and Clock System (CS)

The clock system includes support for a 32-kHz watch crystal oscillator XT1 (LF mode), an internal very-low-power low-frequency oscillator (VLO), an integrated internal digitally controlled oscillator (DCO), and a high-frequency crystal oscillator XT1 (HF mode). The clock system module is designed to meet the requirements of both low system cost and low power consumption. A fail-safe mechanism exists for all crystal sources. The clock system module provides the following clock signals:

  • Auxiliary clock (ACLK), sourced from a 32-kHz watch crystal (XT1 LF mode), a high-frequency crystal (XT1 HF mode), the internal VLO, or the internal DCO.
  • Main clock (MCLK), the system clock used by the CPU. MCLK can be sourced by the same sources made available to ACLK.
  • Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules. SMCLK can be sourced by the same sources made available to ACLK.

6.10.3 Power-Management Module (PMM)

The PMM includes an integrated voltage regulator that supplies the core voltage to the device. The PMM also includes supply voltage supervisor (SVS) and brownout protection. The brownout circuit is implemented to provide the proper internal reset signal to the device during power-on and power-off. The SVS circuitry detects if the supply voltage drops below a user-selectable safe level. SVS circuitry is available on the primary and core supplies.

6.10.4 Hardware Multiplier (MPY)

The multiplication operation is supported by a dedicated peripheral module. The module performs operations with 32-, 24-, 16-, and 8-bit operands. The module supports signed and unsigned multiplication as well as signed and unsigned multiply-and-accumulate operations.

6.10.5 Real-Time Clock (RTC_B)

The RTC_B module contains an integrated real-time clock (RTC) (calendar mode). Calendar mode integrates an internal calendar which compensates for months with fewer than 31 days and includes leap year correction. The RTC_B also supports flexible alarm functions and offset-calibration hardware. RTC operation is available in LPM3.5 mode to minimize power consumption.

6.10.6 Watchdog Timer (WDT_A)

The primary function of the WDT_A module is to perform a controlled system restart after a software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed in an application, the module can be configured as an interval timer and can generate interrupts at selected time intervals.

6.10.7 System Module (SYS)

The SYS module handles many of the system functions within the device. These include power-on reset (POR) and power-up clear (PUC) handling, NMI source selection and management, reset interrupt vector generators (see Table 6-6), bootloader entry mechanisms, and configuration management (device descriptors). It also includes a data exchange mechanism using JTAG called a JTAG mailbox that can be used in the application.

6.10.8 DMA Controller

The DMA controller allows movement of data from one memory address to another without CPU intervention. For example, the DMA controller can be used to move data from the ADC10_B conversion memory to RAM. Using the DMA controller can increase the throughput of peripheral modules. The DMA controller reduces system power consumption by allowing the CPU to remain in sleep mode, without having to awaken to move data to or from a peripheral. Table 6-7 lists all triggers to start DMA transfers.
