The architecture, combined with five low-power modes is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The calibrated digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 s. This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. These devices have limited built-in ESD protection.

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 Constant Generator 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. 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 1 shows examples of the three types of instruction formats; the address modes are listed in Table 2.

The CPU can perform single-byte and single-word writes to the flash memory. Features of the flash memory include: D 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. D Segments 0 to n may be erased in one step, or each segment may be individually erased. D 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. D Segment A contains calibration data. After reset, segment A is protected against programming or erasing. It can be unlocked, but care should be taken not to erase this segment if the calibration data is required. D Flash content integrity check with marginal read modes peripherals Peripherals are connected to the CPU through data, address, and control buses and can be handled using all instructions. For complete module descriptions, see the MSP430x2xx Family User’s Guide, literature number SLAU144. 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 ADC12 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. oscillator and system clock The clock system in the MSP430x241x and MSP43x261x family of devices 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, an internal digitally controlled oscillator (DCO), and a high-frequency crystal oscillator. 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 s. The basic clock module provides the following clock signals: D Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal, a high-frequency crystal, or a very low-power LF oscillator D Main clock (MCLK), the system clock used by the CPU D Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules The DCO settings to calibrate the DCO output frequency are stored in the information memory segment A.

The SVS circuitry detects if the supply voltage drops below a user selectable level and supports both supply voltage supervision (the device is automatically reset) and supply voltage monitoring (SVM) (the device is not automatically reset). The CPU begins code execution after the brownout circuit releases the device reset. However, VCC may not have ramped to VCC(min) at that time. The user must ensure that the default DCO settings are not changed until VCC reaches VCC(min). If desired, the SVS circuit can be used to determine when VCC reaches VCC(min). digital I/O There are up to eight 8-bit I/O ports implemented—ports P1 through P8: D D D D D D 20 All individual I/O bits are independently programmable. Any combination of input, output, and interrupt conditions is possible. Edge-selectable interrupt input capability for all eight bits of ports P1 and P2. Read/write access to port-control registers is supported by all instructions. Each I/O has an individually programmable pullup/pulldown resistor. Ports P7/P8 can be accessed word-wise.

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. hardware multiplier The multiplication operation is supported by a dedicated peripheral module. The module performs 16×16, 16×8, 8×16, and 8×8 bit operations. The module is capable of supporting signed and unsigned multiplication as well as signed and unsigned multiply and accumulate operations. The result of an operation can be accessed immediately after the operands have been loaded into the peripheral registers. No additional clock cycles are required. universal serial communication interface (USCI) The USCI modules are used for serial data communication. The USCI module supports synchronous communication protocols such as SPI (3 pin or 4 pin) or I2C, and asynchronous combination protocols such as UART, enhanced UART with automatic baudrate detection (LIN), and IrDA. The USCI A module provides support for SPI (3 pin or 4 pin), UART, enhanced UART, and IrDA. The USCI B module provides support for SPI (3 pin or 4 pin) and I2C.

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. 5. To improve EMI on the LFXT1 oscillator the following guidelines should be observed. -- Keep the trace between the device and the crystal as short as possible. -- Design a good ground plane around the oscillator pins. -- Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT. -- Avoid running PCB traces under or adjacent to the XIN and XOUT pins. ---- Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins. If conformal coating is used, ensure that it does not induce capacitive/resistive leakage between the oscillator pins. 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.

When activated, a fuse check current, ITF, of 1 mA at 3 V or 2.5 mA at 5 V can flow from the TDI/TCLK pin to ground if the fuse is not burned. Care must be taken to avoid accidentally activating the fuse check mode and increasing overall system power consumption. Activation of the fuse check mode occurs with the first negative edge on the TMS pin after power up or if the TMS is being held low during power up. The second positive edge on the TMS pin deactivates the fuse check mode. After deactivation, the fuse check mode remains inactive until another POR occurs. After each POR the fuse check mode has the potential to be activated. The fuse check current flows only when the fuse check mode is active and the TMS pin is in a low state (see Figure 49). Therefore, the additional current flow can be prevented by holding the TMS pin high (default condition). Time TMS Goes Low After POR TMS ITDI/TCLK ITF Figure 49.
