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.

The CPU is integrated with 16 registers that provide

reduced

instruction

execution

time.

The

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 the original 51

instructions with three formats and seven address

modes and additional instructions for the expanded

address range. Each instruction can operate on word

and byte data. Table 3 shows examples of the three

types of instruction formats; the address modes are

listed in Table 4.

Table 3. Instruction Word Formats

Dual operands, source-destination

e.g., ADD

R4,R5

R4 + R5

→ R5

Single operands, destination only

e.g., CALL

→ (TOS), R8 → PC

Relative jump, un/conditional

e.g., JNE

Jump-on-equal bit = 0
