Syntax

Description

2xx

SQRA

dma

SQRA {

ind} [, next ARP]

√

Square and Accumulate Previous Product

Add the contents of the P register (shifted as specified

by the PM status bits) to the accumulator. Then load

the contents of the addressed data-memory location

into the T register (TMS320C2x/2xx) or TREG0

(TMS320C5x), square the value, and store the result

in the P register.

SQRS

dma

SQRS {

ind} [, next ARP]

√

Square and Subtract Previous Product

Subtract the contents of the P register (shifted as

specified by the PM status bits) to the accumulator.

Then load the contents of the addressed data-memory

location into the T register (TMS320C2x/2xx) or

TREG0 (TMS320C5x), square the value, and store the

result in the P register.

SST

dma

SST {

ind} [, next ARP]

√

Store Status Register

Store the contents of the ST (TMS320C1x) or ST0

(TMS320C2x/2xx/5x) in the addressed data-memory

location.

SST #

n, dma

SST #

n, {ind} [, next ARP]

√

Store Status Register n

Store ST

n in data memory.

SST1

dma

SST1 {

ind} [, next ARP]

√

Store Status Register ST1

Store the contents of ST1 in the addressed

data-memory location.

SSXM

√

Set Sign-Extension Mode

Set the SXM status bit to 1; this enables sign

extension.

STC

√

Set Test/Control Flag

Set the TC flag to 1.

STXM

√

Set Serial Port Transmit Mode

Set the TXM status bit to 1.
