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
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.
The MSP430xG461x device family utilizes the
MSP430X CPU and is completely backwards
compatible with the MSP430 CPU. For a complete
description of the MSP430X CPU, see the
MSP430x4xx Family User’s Guide (SLAU056).
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 1 shows
examples of the three types of instruction formats;
Table 2 shows the address modes.
