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 conjunc-
tion with seven addressing modes for source
operand and four addressing modes for destina-
tion operand.
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 remain-
ing 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.
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
