Store Byte - Analog Devices ADSP-BF53x Blackfin Reference

Instruction Overview

Store Byte

General Form
B [ indirect_address ] = D-register
Syntax
B [ Preg ] = Dreg ;
B [ Preg ++ ] = Dreg ;
B [ Preg -- ] = Dreg ;
B [ Preg + uimm15 ] = Dreg ;
B [ Preg - uimm15 ] = Dreg ;
Syntax Terminology
:
Dreg R7–0
: , ,
Preg P5–0 SP
: 15-bit unsigned field, with a range of 0 through 32,767 bytes
uimm15
(0x0000 through 0x7FFF)
Instruction Length
In the syntax, comment (a) identifies 16-bit instruction length. Comment
(b) identifies 32-bit instruction length.
Functional Description
The Store Byte instruction stores the least significant 8-bit byte of a data
register to an 8-bit memory location. The Pointer register is a P-register.
The indirect address and offset have no restrictions for memory address
alignment.
