description
The MSP430 is an ultralow-power mixed signal microcontroller family consisting of several devices that feature
different sets of modules targeted to various applications. The microcontroller is designed to be battery operated
for an extended application lifetime. With 16-bit RISC architecture, 16-bit integrated registers on the CPU, and
a constant generator, the MSP430 achieves maximum code efficiency. The digitally-controlled oscillator,
together with the frequency-locked-loop (FLL), provides a wakeup from a low-power mode to active mode in
less than 6 ms.

short-form description
processing unit
The processing unit is based on a consistent and orthogonal designed CPU and instruction set. This design
structure results in a RISC-like architecture, highly transparent to the application development and
distinguishable by the ease of programming. All operations other than program-flow instructions are
consequently performed as register operations in conjunction with seven addressing modes for source and four
modes for destination operand.
CPU
Sixteen registers located inside the CPU provide
reduced instruction execution time. This reduces
a register-register operation execution time to one
cycle of the processor frequency.
Program Counter
PC/R0
Stack Pointer
SP/R1
Status Register
Four registers are reserved for special use as a
program counter, a stack pointer, a status register,
and a constant generator. The remaining ones are
available as general-purpose registers.

General-Purpose Register
architecture provides a powerful and easy-to-use
assembly language. The instruction set consists of 51 instructions with three formats and seven addressing
modes. Table 1 provides a summation and example of the three types of instruction formats; the addressing
modes are listed in Table 2.
Table 1. Instruction Word Formats
Dual operands, source-destination
e.g. ADD R4, R5
R4 + R5 → R5
Single operands, destination only
e.g. CALL R8
PC → (TOS), R8 → PC
Relative jump, un-/conditional
e.g. JNE
Jump-on equal bit = 0
Each instruction that operates on word and byte data is identified by the suffix B.

Computed branches (BR) and subroutine call (CALL) instructions use the same addressing modes as the other
instructions. These addressing modes provide indirect addressing, ideally suited for computed branches and
calls. The full use of this programming capability permits a program structure different from conventional 8- and
16-bit controllers. For example, numerous routines can easily be designed to deal with pointers and stacks
instead of using flag type programs for flow control.
operation modes and interrupts
The MSP430 operating modes support various advanced requirements for ultra low-power and ultra-low energy
consumption. This is achieved by the management of the operations during the different module operation
modes and CPU states. The requirements are fully supported during interrupt event handling. An interrupt event
awakens the system from each of the various operating modes and returns with the RETI instruction to the mode
that was selected before the interrupt event. The clocks used are ACLK and MCLK. ACLK is the crystal
frequency and MCLK , a multiple of ACLK, is used as the system clock.
The software can configure five operating modes:
D
D
D
D
D
D
Active mode (AM). The CPU is enabled with different combinations of active peripheral modules.
Low-power mode 0 (LPM0). The CPU is disabled, peripheral operation continues, ACLK and MCLK signals
are active, and loop control for MCLK is active.
Low-power mode 1 (LPM1). The CPU is disabled, peripheral operation continues, ACLK and MCLK signals
are active, and loop control for MCLK is inactive.
Low-power mode 2 (LPM2). The CPU is disabled, peripheral operation continues, ACLK signal is active,
and MCLK and loop control for MCLK are inactive.
Low-power mode 3 (LPM3). The CPU is disabled, peripheral operation continues, ACLK signal is active,
MCLK and loop control for MCLK are inactive, and the dc generator for the digital controlled oscillator (DCO)
( MCLK generator) is switched off.
³
Low-power mode 4 (LPM4). The CPU is disabled, peripheral operation continues, ACLK signal is inactive
(crystal oscillator stopped), MCLK and loop control for MCLK are inactive, and the dc generator for the DCO
is switched off.
The special function registers (SFR) include module-enable bits that stop or enable the operation of the specific
peripheral module. All registers of the peripherals may be accessed if the operational function is stopped or
enabled. However, some peripheral current-saving functions are accessed through the state of local register
bits. An example is the enable/disable of the analog voltage generator in the LCD peripheral, which is turned
on or off using one register bit.

peripherals
Peripherals connected to the CPU through a data, address, and control busses can be handled easily with
instructions for memory manipulation.
oscillator and system clock
Two clocks are used in the system: the system (master) clock (MCLK) and the auxiliary clock (ACLK). The MCLK
is a multiple of the ACLK. The ACLK runs with the crystal oscillator frequency. The special design of the oscillator
supports the feature of low current consumption and the use of a 32 768 Hz crystal. The crystal is connected
across two terminals without requiring any other external components.
The oscillator starts after applying VCC, due to a reset of the control bit (OscOff) in the status register (SR). It
can be stopped by setting the OscOff bit to a 1. The enabled clock signals ACLK, ACLK/2, ACLK/4, or MCLK
are accessible for use by external devices at output terminal XBUF.
The controller system clock has to operate with different requirements according to the application and system
conditions. Requirements include:
•
•
•
•
High frequency in order to react quickly to system hardware requests or events
Low frequency in order to minimize current consumption, EMI, etc.
Stable frequency for timer applications e.g. real-time clock (RTC)
Enable start-stop operation with a minimum delay
These requirements cannot all be met with fast frequency high-Q crystals or with RC-type low-Q oscillators. The
compromise selected for the MSP430 uses a low-crystal frequency, which is multiplied to achieve the desired
nominal operating range:
f(system) = (N+1) × f(crystal)
The crystal frequency multiplication is achieved with a frequency locked loop (FLL) technique. The factor N is
set to 31 after a power-up clear condition. The FLL technique, in combination with a digital controlled oscillator
(DCO), provides immediate start-up capability together with long-term crystal stability. The frequency variation
of the DCO with the FLL inactive is typically 330 ppm, which means that with a cycle time of 1 µs, the maximum
possible variation is 0.33 ns. For more precise timing, the FLL can be used. This forces longer cycle times if
the previous cycle time was shorter than the selected one. This switching of cycle times makes it possible to
meet the chosen system frequency over a long period of time.
The start-up operation of the system clock depends on the previous machine state. During a power-up clear
(PUC), the DCO is reset to its lowest possible frequency. The control logic starts operation immediately after
removal of the PUC condition. Correct operation of the FLL control logic requires the presence of a stable crystal
oscillator.

peripherals (continued)
digital I/O
There is one eight-bit I/O port, Port0, that is implemented (MSP430C311S and MSP430P315S have six bits
available on external pins). Six control registers give maximum digital input/output flexibility to the application:
•
•
•
•
All individual I/O bits are programmable independently.
Any combination of input, output, and interrupt conditions is possible.
Interrupt processing of external events is fully implemented for all eight bits of port P0.
Provides read/write access to all registers with all instructions
The six registers are:
•
•
•
•
•
•
Input register
8 bits
contains information at the pins
Output register
8 bits
contains output information
Direction register
8 bits
controls direction
Interrupt flags
6 bits
indicates if interrupt(s) are pending
Interrupt edge select
8 bits
contains input signal change necessary for interrupt
Interrupt enable
6 bits
contains interrupt enable bits
All these registers contain eight bits except for the interrupt flag register and the interrupt enable register. The
two least significant bits (LSBs) of the interrupt flag and interrupt enable registers are located in the special
functions register (SFR). Three interrupt vectors are implemented, one for Port0.0, one for Port0.1, and one
commonly used for any interrupt event on Port0.2 to Port0.7. The Port0.1 and Port0.2 pin function is shared with
the 8-bit timer/counter.
LCD drive
Liquid crystal displays (LCDs) for static, 2-, 3-, and 4-MUX operations can be driven directly. The controller LCD
logic operation is defined by software using memory-bit manipulation. LCD memory is part of the LCD module
and not part of the data memory. Eight mode and control bits define the operation and current consumption of
the LCD drive. The information for the individual digits can be easily obtained using table programming
techniques combined with the correct addressing mode. The segment information is stored in LCD memory
using instructions for memory manipulation.
The drive capability is mainly defined by the external resistor divider that supports the analog levels for 2-, 3-,
and 4-MUX operation. Groups of the LCD segment lines can be selected for digital output signals. The
MSP430x31x has four common signals and 23 segment lines. The MSP430C311S and MSP430P315S have
four common lines and 16 segment lines.
Timer/Port
The Timer/Port module has two 8-bit counters, an input that triggers one counter, and six digital outputs in the
MSP430x31x (MSP430C311S, MSP430C315S have five digital outputs available on external pins) with
high-impedance state capability. Both counters have an independent clock-selector for selecting an external
signal or one of the internal clocks (ACLK or MCLK). One counter has an extended control capability to halt,
count continuously, or gate the counter by selecting one of two external signals. This gate signal sets the
interrupt flag, if an external signal is selected, and the gate stops the counter.
Both timers can be read from and written to by software. The two 8-bit counters can be cascaded to a 16-bit
counter. A common interrupt vector is implemented. The interrupt flag can be set from three events in the 8-bit
counter mode (gate signal, overflow from the counters) or from two events in the 16-bit counter mode (gate
signal, overflow from the MSB of the cascaded counter).

peripherals (continued)
slope A/D conversion
Slope A/D conversion is accomplished with the timer/port module using external resistor(s) for reference (Rref),
external resistor(s) to the measured (Rmeas), and an external capacitor. The external components are driven
by software in such a way that the internal counter measures the time that is needed to charge or discharge
the capacitor. The reference resistor’s (Rref) charge or discharge time is represented by Nref counts. The
unknown resistors (Rmeas) charge or discharge time is represented by Nmeas counts. The unknown resistor’s
value (Rmeas) is the value of Rref multiplied by the relative number of counts (Nmeas/Nref). This value determines
resistive sensor values that correspond to the physical data, for example temperature, when an NTC or PTC
resistor is used.
Basic Timer1
The Basic Timer1 (BT1) divides the frequency of MCLK or ACLK, as selected with the SSEL bit, to provide low
frequency control signals. This is done within the system by one central divider, the basic timer1, to support low
current applications. The BTCTL control register contains the flags which controls or selects the different
operational functions. When the supply voltage is applied or when a reset of the device (RST/NMI pin), a
watchdog overflow, or a watchdog security key violation occurs, all bits in the register hold undefined or
unchanged status. The user software usually configures the operational conditions on the BT1 during
initialization.
The Basic Timer1 has two 8 bit timers which can be cascaded to a 16 bit timer. Both timers can be read and
written by software. Two bits in the SFR address range handle the system control interaction according to the
function implemented in the Basic Timer1. These two bits are the Basic Timer1 interrupt flag (BTIFG) and the
basic timer interrupt enable (BTIE) bit.
Watchdog Timer
The primary function of the Watchdog Timer (WDT) module is to perform a controlled system restart after a
software problem has occurred. If the selected time interval expires, a system reset is generated. If this
watchdog function is not needed in an application, the module can work as an interval timer, which generates
an interrupt after the selected time interval.
The Watchdog Timer counter (WDTCNT) is a 15/16-bit up-counter which is not directly accessible by software.
The WDTCNT is controlled using the Watchdog Timer control register (WDTCTL), which is a 16-bit read/write
register. Writing to WDTCTL, in both operating modes (watchdog or timer) is only possible by using the correct
password in the high-byte. The low-byte stores data written to the WDTCTL. The high-byte password is 05Ah.
If any value other than 05Ah is written to the high-byte of the WDTCTL, a system reset PUC is generated. When
the password is read its value is 069h. This minimizes accidental write operations to the WDTCTL register. In
addition to the Watchdog Timer control bits, there are two bits included in the WDTCTL which configure the NMI
pin.
8-Bit Timer/Counter
The 8-bit interval timer supports three major functions for the application:
• Serial communication or data exchange
• Pulse counting or pulse accumulation
• Timer
The 8-bit Timer/Counter peripheral includes the following major blocks: an 8-bit up-counter with
preload-register, an 8-bit control register, an input clock selector, an edge detection (e.g. start bit detection for
asynchronous protocols), and an input and output data latch, triggered by the carry-out-signal from the 8-bit
counter.
The 8-bit counter counts up with an input clock, which is selected by two control bits from the control register.
The four possible clock sources are MCLK, ACLK, the external signal from terminal P0.1, and the signal from
the logical AND of MCLK and terminal P0.1.

MIXED SIGNAL MICROCONTROLLERS
SLAS165D – FEBRUARY 1998 – REVISED APRIL 2000
8-Bit Timer/Counter (continued)
Two counter inputs (load, enable) control the counter operation. The load input controls load operations. A
write-access to the counter results in loading the content of the preload-register into the counter. The software
writes or reads the preload-register with all instructions. The preload-register acts as a buffer and can be written
immediately after the load of the counter is completed. The enable input enables the count operation. When
the enable signal is set to high, the counter will count up each time a positive clock edge is applied to the clock
input of the counter.
Serial protocols, like UART protocol, need start-bit edge-detection to determine, at the receiver, the start of a
data transmission. When this function is activated, the counter starts counting after start-bit condition is
detected. The first signal level is sampled into the RXD input data-latch after completing the first timing interval,
which is programmed into the counter. Two latches used for input and output data (RXD_FF and TXD_FF) are
clocked by the counter after the programmed timing interval has elapsed.
UART
The serial communication is realized by using software and the 8-bit timer/counter hardware. The hardware
supports the output of the serial data stream, bit-by-bit, with the timing determined by the counter. The
software/hardware interface connects the mixed signal controller to external devices, systems, or networks.

TYPICAL CHARACTERISTICS
JTAG fuse check mode
MSP430 devices that have the fuse on the TDI/VPP 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 TDI/VPP 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 after 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.

NOTES: A. During programming activity and when blowing the JTAG enable fuse, the TDI/VPP terminal is used to apply the correct voltage
source. The TDO/TDI terminal is used to apply the test input data for JTAG circuitry.
B. The TDI/VPP terminal of the ’P31x and ’E31x does not have an internal pullup resistor. An external pulldown resistor is
recommended to avoid a floating node, which could increase the current consumption of the device.
C. The TDO/TDI terminal is in a high-impedance state after POR. The ’P31x and ’E31x need a pullup or a pulldown resistor to avoid
floating a node, which could increase the current consumption of the device.
