Instruction Syntax and Addressing Modes

4.3 Instruction Syntax and Addressing Modes

MSP50P614/MSP50C614 instructions can perform multiple operations per instruction. Many instructions may have multiple source arguments. They can premodify register values and can have only one destination. The addressing mode is part of the source and destination arguments. In the following subsec- tion, a detail of the MSP50P614/MSP50C614 instruction syntax is explained followed by the subsection which describes addressing modes.

4.3.1MSP50P614/MSP50C614 Instruction Syntax

All MSP50P614/MSP50C614 instructions with multiple arguments have the following syntax:

name [dest] [, src] [, src1] [, mod]

where the symbols are described as follows:

name

name of the instruction. Instruction names are shown in bold letters. If the

 

instruction name is followed by a B, the arguments are all byte types. If

 

name is followed by an S, all arguments are word string (strings of words)

 

types. If name is followed by BS, all arguments are byte string types.

dest

destination of data to be stored after the execution of an instruction. Op-

 

tional or not used for some instructions. Destination is also used as both a

 

source and a destination for some instructions. If a destination is specified,

 

it must always be the first argument. Destinations can be system registers

 

or data memory locations referred by addressing modes. This is instruc-

 

tion specific.

src

source of first data. Optional or not used for some instruction. Source can

 

be a system register, a data memory location referred by addressing

 

modes, or a program memory location. This is instruction specific.

src1

source of second data. Some instructions use a second data source. Op-

 

tional or not used for some instructions. Source 1 can be a system register,

 

a data memory location referred by addressing modes, or a program

 

memory location. This is instruction specific.

mod

pre or post modification of a register. The meaning of mod is instruction

 

specific.

[ ]

Square brackets represent optional arguments. Some instructions have

 

many combinations of source and destination registers and addressing

 

modes. The combination is instruction class specific.

The possible combinations of sources, destinations and modifications are de- pendent on the instruction class. Instruction classes are discussed in detail in section 4.4.
