(1) To improve EMI on the XT1 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 underneath or adjacent to the XIN and XOUT pins.
• Use assembly materials and processes that avoid any parasitic load on the oscillator XIN and XOUT pins.
• If conformal coating is used, make sure that it does not induce capacitive or 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.
(2) 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 crystal that is used.
(3) Frequencies below the MIN specification set the fault flag. Frequencies above the MAX specification do not set the fault flag.
Frequencies between the MIN and MAX specifications might set the flag.
(4) Measured with logic-level input frequency but also applies to operation with crystals.

6 Detailed Description
6.1 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-to­register 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.

6.3 Operating Modes
The MSP430 microcontrollers have one active mode and five software-selectable low-power modes of operation. An interrupt event can wake up the device from any of the five 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 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 dc-generator remains enabled.
Low-power mode 3 (LPM3) – CPU is disabled. – ACLK remains active. – MCLK and SMCLK are disabled. – DCO dc-generator is disabled.
Low-power mode 4 (LPM4) – CPU is disabled. – ACLK, MCLK, and SMCLK are disabled. – DCO dc-generator is disabled. – Crystal oscillator is stopped.

6.4 Interrupt Vector Addresses
The interrupt vectors and the power-up starting address are located in the address range of 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, if flash is not programmed), the CPU goes into LPM4 immediately after power up.

(1) A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0h to 01FFh) or from
within unused address range. (2) Multiple source flags (3) (non)-maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot.
Nonmaskable: neither the individual nor the general interrupt-enable bit will disable an interrupt event. (4) Interrupt flags are located in the module. (5) This location is used as bootstrap loader security key (BSLSKEY).
A 0AA55h at this location disables the BSL completely.
A zero (0h) disables the erasure of the flash if an invalid password is supplied. (6) The interrupt vectors at addresses 0FFDCh to 0FFC0h are not used in this device and can be used for regular program code if
necessary.

6.7 Bootstrap Loader (BSL)
The MSP430 bootstrap loader (BSL) enables users to program the flash memory or RAM using a UART serial interface. 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 6-9. BSL Function Pins

Data transmit 32 - P1.1 30 - P1.1 G3 - P1.1
Data receive 10 - P2.2 8 - P2.2 A5 - P2.2
6.8 Flash Memory
The flash memory can be programmed via the JTAG port, the bootstrap loader, 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.

6.9 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 (SLAU144).
6.10 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, 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 turn­on clock source and stabilizes in less than 1 µs. The basic clock module provides the following clock signals:
Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal, a high-frequency crystal, or the internal very-low-power 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.

6.11 Brownout
The brownout circuit is implemented to provide the proper internal reset signal to the device during power on and power off.
6.12 Digital I/O
There are four 8-bit I/O ports implemented—ports P1, P2, P3, and P4:
All individual I/O bits are independently programmable.
Any combination of input, output, and interrupt condition is possible.
Edge-selectable interrupt input capability for all eight bits of port P1 and 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.
6.13 Watchdog Timer (WDT+)
The primary function of the 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.

6.19.19 JTAG Fuse Check Mode
MSP430 devices that have the fuse on the TEST terminal have a fuse check mode that tests the continuity of the fuse the first time the JTAG port is accessed after a power-on reset (POR). When activated, a fuse check current, ITF, of 1 mA at 3 V, 2.5 mA at 5 V can flow from the TEST 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.
When the TEST pin is again taken low after a test or programming session, the fuse check mode and sense currents are terminated.
Activation of the fuse check mode occurs with the first negative edge on the TMS pin after power up or if TMS is 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 6-1). Therefore, the additional current flow can be prevented by holding the TMS pin high (default condition).
www.ti.com
Figure 6-1. Fuse Check Mode Current
NOTE
The CODE and RAM data protection is ensured if the JTAG fuse is blown and the 256-bit bootloader access key is used. Also, see the Bootstrap Loader section for more information.

7.1.3 Device and Development Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all MSP430 MCU devices and support tools. Each MSP430 MCU commercial family member has one of three prefixes: MSP, PMS, or XMS (for example, MSP430F5259). Texas Instruments recommends two of three possible prefix designators for its support tools: MSP and MSPX. These prefixes represent evolutionary stages of product development from engineering prototypes (with XMS for devices and MSPX for tools) through fully qualified production devices and tools (with MSP for devices and MSP for tools).
Device development evolutionary flow:
www.ti.com
XMS – Experimental device that is not necessarily representative of the final device's electrical
specifications PMS – Final silicon die that conforms to the device's electrical specifications but has not completed quality
and reliability verification MSP – Fully qualified production device Support tool development evolutionary flow: MSPX – Development-support product that has not yet completed Texas Instruments internal qualification
testing. MSP – Fully-qualified development-support product XMS and PMS devices and MSPX development-support tools are shipped against the following
disclaimer: "Developmental product is intended for internal evaluation purposes." MSP devices and MSP development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices (XMS and PMS) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, PZP) and temperature range (for example, T). Figure 7-1 provides a legend for reading the complete device name for any family member.
