short-form description
processing unit
The processing unit is based on a consistent and orthogonally-designed CPU and instruction set. This design
structure results in a RISC-like architecture, highly transparent to the application development and is
distinguished due to 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.
Program Counter
PC/R0
Stack Pointer
SP/R1
CPU
Sixteen registers are located inside the CPU,
providing reduced instruction execution time. This
reduces a register-register operation execution
time to one cycle of the processor frequency.
Status Register
Constant Generator
Four of the registers are reserved for special
use as a program counter, a stack pointer, a status
register and a constant generator. The remaining
registers are available as general-purpose
registers.
Peripherals are connected to the CPU using a
data address and control bus and can be handled
easily with all instructions for memory
manipulation.

instruction set
The instruction set for this register-register architecture provides a powerful and easy-to-use assembler
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.
Examples:

OPERATION

d = destination
Computed branches (BR) and subroutine calls (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 intelligent 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 is a multiple of ACLK and 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.

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 any other external components being required.
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.

oscillator and system clock (continued)
The controller system clock has to operate with different requirements according to the application and system
conditions. Requirements include:
D
D
D
D
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 of 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 acheived 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 which 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
recognition of PUC. Connect operation of the FLL control logic requires the presence of a stable crystal
oscillator.
digital I/O
One 8-bit I/O port (Port0) is implemented. Six control registers give maximum flexibility of digital input/output
to the application:
D

D
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.

All six registers contain eight bits except for the interrupt flag register and the interrupt enable register. The two
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,
not part of 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-, 3and 4-MUX operation. Groups of the LCD segment lines can be selected for digital output signals. The
MSP430x32x configuration has four common signal lines and 21 segment lines.
A/D converter
The analog-to-digital converter (ADC) is a cascaded converter type that converts analog signals from VCC to
GND. It is a 12+2 bit converter with a software or automatically-controlled range select. Five inputs can be
selected for analog or digital function. A ratiometric current source can be used on four of the analog pins. The
current is adjusted by an external resistor and is enabled/disabled by bits located in the control registers. The
conversion is started by setting the start-of-conversion bit (SOC) in the control register and the
end-of-conversions sets the interrupt flag. The analog input signal is sampled starting with SOC during the next
twelve MCLK clock pulses. The power-down bit in the control register controls the operating mode of the ADC
peripheral. The current consumption and operation is stopped when it is set. The system reset PUC sets the
power-down bit.
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 Timer1 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 upset 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 an 8-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 it’s value is 069h. This minimizes accidental write operations to the WDTCTL register. In
addition to the Watchdog Timer control bits, two bits included in the WDTCTL configure the NMI pin.

8-bit Timer/Counter
The 8-bit interval timer supports three major functions for the application:
D
D
D
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.
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 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 the 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 are 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.
Timer/Port
The Timer/Port module has two 8-bit counters, an input that triggers one counter, and six 3-state digital outputs.
Both counters have an independent clock-selector for selecting an external signal or one of the internal clocks
(ACLK or MCLK). One of the counters 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).

21. Once the JTAG fuse is blown, no further access to the MSP430 JTAG/test feature is possible. The JTAG block switches to by-pass
mode.
22. The voltage supply to blow the JTAG fuse is applied to TDI/VPP pin when fuse blowing is desired.

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 ’P325A and ’E325A 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 ’P325A and ’E325A needs a pullup or a pulldown resistor to avoid
floating a node which could increase the current consumption of the device.

SLAS219B – MARCH 1999 – REVISED MARCH 2000
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 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.
