description
The Texas Instruments MSP430 family of ultralow
power microcontrollers consist of several devices
featuring different sets of peripherals targeted for
various applications. 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 attribute to maximum code
efficiency. The digitally controlled oscillator (DCO)
allows wake-up from low-power modes to active
mode in less than 6µs.

The MSP430x11x series is an ultra low-power mixed signal microcontroller with a built in 16-bit timer and
fourteen I/O pins.
Typical applications include sensor systems that capture analog signals, convert them to digital values, and then
process the data and display them or transmit them to a host system. Stand alone RF sensor front-end is another
area of application.

short-form description
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.
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.

operating modes
The MSP430 has 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:
D Active mode AM;
−
All clocks are active
D Low-power mode 0 (LPM0);
−

ACLK and SMCLK remain active. MCLK is disabled
D Low-power mode 1 (LPM1);

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 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 6 µs. The basic clock module provides the
following clock signals:
D Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal or a high frequency crystal.
D Main clock (MCLK), the system clock used by the CPU.
D Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules.
digital I/O
There are two 8-bit I/O ports implemented—ports P1 and P2 (only six P2 I/O signals are available on external
pins):
D
D
D
D
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 the eight bits of port P1 and six bits of port P2.
Read/write access to port-control registers is supported by all instructions.
NOTE:
Six bits of Port P2, P2.0 to P2.5, are available on external pins − but all control and data bits for Port
P2 are implemented.

SLAS196D− DECEMBER 1998 − REVISED SEPTEMBER 2004
watchdog timer
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 configured as an interval timer and can generate
interrupts at selected time intervals.
timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.

capture may be triggered with capture signals even shorter than tcap. Both the cycle and timing specifications must be met to ensure
a correct capture of the 16-bit timer value and to ensure the flag is set.

main DCO characteristics
D Individual devices have a minimum and maximum operation frequency. The specified parameters for
f(DCOx0) to f(DCOx7) are valid for all devices.
D All ranges selected by Rsel(n) overlap with Rsel(n+1): Rsel0 overlaps Rsel1, ... Rsel6 overlaps Rsel7.
D DCO control bits DCO0, DCO1, and DCO2 have a step size as defined by parameter SDCO.
D Modulation control bits MOD0 to MOD4 select how often f(DCO+1) is used within the period of 32 DCOCLK
cycles. The frequency f(DCO) is used for the remaining cycles. The frequency is an average equal to:

APPLICATION INFORMATION
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 taken back 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 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 will only flow when the fuse check mode is active and the TMS pin is in a low state (see
Figure 6). Therefore, the additional current flow can be prevented by holding the TMS pin high (default
condition).
