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. Program Counter PC/R0 Stack Pointer SP/R1 SR/CG1/R2 Status Register The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-toregister operation execution time is one cycle of the CPU clock. Constant Generator 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. Instruction Set The instruction set consists of 51 instructions with three formats and seven address modes. Each instruction can operate on word and byte data. Table 3 shows examples of the three types of instruction formats; Table 4 shows the address modes.

An interrupt event can wake up the device from any of the low-power modes, service the request, and restore back to the low-power mode on return from the interrupt program. The following six operating modes can be configured by software: • Active mode (AM) – All clocks are active. • Low-power mode 0 (LPM0) – CPU is disabled. – ACLK and SMCLK remain active. – MCLK is disabled. • Low-power mode 1 (LPM1) – CPU is disabled – ACLK and SMCLK remain active. – MCLK is disabled. – DCO's dc generator is disabled if DCO not used in active mode. • Low-power mode 2 (LPM2) – CPU is disabled. – ACLK remains active. – MCLK and SMCLK are disabled. – DCO's dc generator remains enabled. • Low-power mode 3 (LPM3) – CPU is disabled. – ACLK remains active. – MCLK and SMCLK are disabled. – DCO's dc generator is disabled. • Low-power mode 4 (LPM4) – CPU is disabled. – ACLK, MCLK, and SMCLK are disabled. – DCO's dc generator is disabled. – Crystal oscillator is stopped. 8 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: MSP430G2955 MSP430G2855 MSP430G2755 MSP430G2955 MSP430G2855 MSP430G2755 www.ti.com SLAS800 – MARCH 2013 Interrupt Vector Addresses The interrupt vectors and the power-up starting address are located in the address range 0FFFFh to 0FFC0h. The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence. If the reset vector (located at address 0FFFEh) contains 0FFFFh (for example, flash is not programmed), the CPU goes into LPM4 immediately after power-up. Table 5.

Access to the MSP430 memory via the BSL is protected by user-defined password. For complete description of the features of the BSL and its implementation, see the MSP430 Programming Via the Bootstrap Loader User's Guide (SLAU319). Table 9. BSL Function Pins BSL FUNCTION DA PACKAGE PINS RHA PACKAGE PINS Data transmit 32 - P1.1 30 - P1.1 Data receive 10 - P2.2 8 - P2.2 Flash Memory The flash memory can be programmed via the Spy-Bi-Wire or JTAG port or in-system by the CPU. The CPU can perform single-byte and single-word writes to the flash memory. Features of the flash memory include: • Flash memory has n segments of main memory and four segments of information memory (A to D) of 64 bytes each. Each segment in main memory is 512 bytes in size. • Segments 0 to n may be erased in one step, or each segment may be individually erased. • Segments A to D can be erased individually or as a group with segments 0 to n. Segments A to D are also called information memory. • Segment A contains calibration data. After reset segment A is protected against programming and erasing. It can be unlocked but care should be taken not to erase this segment if the device-specific calibration data is required.

For complete module descriptions, see the MSP430x2xx Family User's Guide (SLAU144). Oscillator and System Clock The clock system is supported by the basic clock module that includes support for a 32768-Hz watch crystal oscillator, an internal very-low-power low-frequency oscillator and an internal digitally controlled oscillator (DCO). The basic clock module is designed to meet the requirements of both low system cost and low power consumption. The internal DCO provides a fast turn-on clock source and stabilizes in less than 1 µs. The basic clock module provides the following clock signals: • Auxiliary clock (ACLK), sourced either from a 32768-Hz watch crystal or the internal LF oscillator. • Main clock (MCLK), the system clock used by the CPU. • Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules. The DCO settings to calibrate the DCO output frequency are stored in the information memory segment A. Main DCO Characteristics • All ranges selected by RSELx overlap with RSELx + 1: RSELx = 0 overlaps RSELx = 1, ... RSELx = 14 overlaps RSELx = 15. • DCO control bits DCOx have a step size as defined by parameter SDCO. • Modulation control bits MODx select how often fDCO(RSEL,DCO+1) is used within the period of 32 DCOCLK cycles. The frequency fDCO(RSEL,DCO) is used for the remaining cycles. The frequency is an average equal to: faverage = 12 32 × fDCO(RSEL,DCO) × fDCO(RSEL,DCO+1) MOD × fDCO(RSEL,DCO) + (32 – MOD) × fDCO(RSEL,DCO+1) Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: MSP430G2955 MSP430G2855 MSP430G2755 MSP430G2955 MSP430G2855 MSP430G2755 www.ti.com SLAS800 – MARCH 2013 Calibration Data Stored in Information Memory Segment A Calibration data is stored for both the DCO and for ADC10 organized in a tag-length-value (TLV) structure.

Digital I/O Four 8-bit I/O ports are implemented: • All individual I/O bits are independently programmable. • Any combination of input, output, and interrupt condition (port P1 and port P2 only) is possible. • Edge-selectable interrupt input capability for all bits of port P1 and port P2. • Read and write access to port-control registers is supported by all instructions. • Each I/O has an individually programmable pullup or pulldown resistor. • Each I/O has an individually programmable pin oscillator enable bit to enable low-cost touch sensing. Watchdog Timer (WDT+) The primary function of the watchdog timer (WDT+) 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 disabled or configured as an interval timer and can generate interrupts at selected time intervals.

(a) Keep the trace between the device and the crystal as short as possible. (b) Design a good ground plane around the oscillator pins. (c) Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT. (d) Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins. (e) Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins. (f) If conformal coating is used, ensure that it does not induce capacitive or resistive leakage between the oscillator pins. (g) Do not route the XOUT line to the JTAG header to support the serial programming adapter as shown in other documentation. This signal is no longer required for the serial programming adapter. Includes parasitic bond and package capacitance (approximately 2 pF per pin). Because the PCB adds additional capacitance, it is recommended to verify the correct load by measuring the ACLK frequency.

(b) Design a good ground plane around the oscillator pins. (c) Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT. (d) Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins. (e) Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins. (f) If conformal coating is used, ensure that it does not induce capacitive or resistive leakage between the oscillator pins. (g) Do not route the XOUT line to the JTAG header to support the serial programming adapter as shown in other documentation. This signal is no longer required for the serial programming adapter. Includes parasitic bond and package capacitance (approximately 2 pF per pin). Because the PCB adds additional capacitance, it is recommended to verify the correct load by measuring the ACLK frequency. For a correct setup, the effective load capacitance should always match the specification of the used crystal. Requires external capacitors at both terminals. Values are specified by crystal manufacturers. Frequencies below the MIN specification set the fault flag, frequencies above the MAX specification do not set the fault flag, and frequencies in between might set the flag.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Addendum-Page 1 Samples PACKAGE OPTION ADDENDUM www.ti.com 5-Jun-2013 Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device.

In no event shall TI's liability arising out of such information exceed the total purchase price of the TI part(s) at issue in this document sold by TI to Customer on an annual basis. Addendum-Page 2 IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use.
