TMS320C1x/C2x/C20x/C5x Instruction Set Comparison

Syntax

Description

2xx

dma

{

ind} [, next ARP]

lk [, shift]

√

OR With Accumulator

TMS320C1x and TMS320C2x devices: OR the 16

LSBs of the accumulator with the contents of the

addressed data-memory location. The 16 MSBs of the

accumulator are ORed with 0s.

TMS320C20x and TMS320C5x devices: OR the 16

LSBs of the accumulator or a 16-bit immediate value

with the contents of the addressed data-memory

location. If a shift is specified, left-shift before ORing.

Low-order bits below and high-order bits above the

shifted value are treated as 0s.

ORB

√

OR ACCB With Accumulator

OR the contents of the ACCB with the contents of the

accumulator.

ORB

places

the

result

the

accumulator.

ORK #

lk [, shift]

√

OR Immediate With Accumulator with Shift

OR a 16-bit immediate value with the contents of the

accumulator. If a shift is specified, left-shift the

constant before ORing. Low-order bits below and

high-order bits above the shifted value are treated as

0s.

OUT

dma, PA

OUT {

ind}, PA [, next ARP]

√

Output Data to Port

Write a 16-bit value from a data-memory location to the

specified I/O port.

TMS320C1x devices: The first cycle of this instruction

places

the

port

address

onto

address

lines

A2/PA2–A0/PA0. During the same cycle, WE goes low

and the data word is placed on the data bus D15–D0.

TMS320C2x,

TMS320C20x,

and

TMS320C5x

devices: The IS line goes low to indicate an I/O access;

the STRB, R/W, and READY timings are the same as

for an external data-memory write.

PAC

√

Load Accumulator With P Register

Load the contents of the P register into the

accumulator.

TMS320C2x,

TMS320C20x,

and

TMS320C5x

devices: Before the load, shift the P register as

specified by the PM status bits.
