instruction set summary

Table 2 lists the symbols and abbreviations used in Table 3, the TMS320C25 instruction set summary. Table 3 consists primarily of single-cycle, single-word instructions. Infrequently used branch, I/O, and CALL instructions are multicycle. The instruction set summary is arranged according to function and alphabetized within each functional grouping. The symbol (² ) indicates those instructions that are not included in the TMS320C1x instruction set. The symbol (³ ) indicates instructions that are not included in the TMS32020 instruction set.

	Table 2. Instruction Symbols

SYMBOL	DEFINITION

B	4-bit field specifying a bit code
CM	2-bit field specifying compare mode
D	Data memory address field
FO	Format status bit
I	Addressing mode bit
K	Immediate operand field
PA	Port address (PA0 through PA15 are predefined assembler symbols
	equal to 0 through 15, respectively.)
PM	2-bit field specifying P register output shift code
AR	3-bit operand field specifying auxiliary register
S	4-bit left-shift code
X	3-bit accumulator left-shift field
