Syntax

Description

2xx

LDP

LDP {

ind} [, next ARP]

LDP #

√

Load Data-Memory Page Pointer

TMS320C1x devices: Load the LSB of the contents of

the addressed data-memory location into the DP

page 0 (words 0–127), and DP = 1 defines page 1

(words 128–143/255).

TMS320C2x,

TMS320C20x,

and

TMS320C5x

devices: Load the 9 LSBs of the addressed

data-memory location or a 9-bit immediate value into

the DP register. The DP and 7-bit data-memory

address are concatenated to form 16-bit data-memory

addresses.

LDPK

1-bit constant

LDPK

9-bit constant

√

Load Data-Memory Page Pointer Immediate

TMS320C1x devices: Load a 1-bit immediate value

into the DP register. DP = 0 defines page 0 (words

0–127),

and

DP = 1 defines page 1 (words

128–143/255).

TMS320C2x,

TMS320C20x,

and

TMS320C5x

devices: Load a 9-bit immediate into the DP register.

The

and

7-bit

data-memory

address

are

concatenated to form 16-bit data-memory addresses.

w 8 specifies external data memory. DP = 4

through 7 specifies on-chip RAM blocks B0 or B1.

Block B2 is located in the upper 32 words of page 0.

LMMR

dma, #lk

LMMR {

ind}, #lk [, next ARP]

√

Load Memory-Mapped Register

Load the contents of the memory-mapped register

pointed at by the 7 LSBs of the direct or indirect

data-memory value into the long immediate addressed

data-memory

location.

The

MSBs

the

data-memory address are cleared, regardless of the

current value of DP or the 9 MSBs of AR (ARP).

LPH

dma

LPH {

ind} [, next ARP]

√

Load High P Register

Load the contents of the addressed data-memory

location into the 16 MSBs of the P register; the LSBs

are not affected.

LRLK

AR, lk

√

Load Auxiliary Register Long Immediate

Load a 16-bit immediate value into the designated

auxiliary register.

LST

dma

LST {

ind} [, next ARP]

√

Load Status Register

Load the contents of the addressed data-memory

location into the ST (TMS320C1x) or into ST0

(TMS320C2x/2xx/5x).
