Move Byte – Zero-Extended
General Form
dest_reg = src_reg_byte (Z)
Syntax
Dreg = Dreg_byte (Z) ;
Syntax Terminology
:
Dreg_byte R7–0.B
Instruction Length
In the syntax, comment (a) identifies 16-bit instruction length.
Functional Description
The Move Byte – Zero-Extended instruction converts an unsigned byte to
an unsigned word (32 bits). The instruction copies the least significant 8
bits from a source register into the least significant 8 bits of a 32-bit regis-
ter. The instruction zero-extends the upper bits of the destination register.
This instruction supports only D-registers.
Flags Affected
The following flags are affected by the Move Byte – Zero-Extended
instruction.
• is set if result is zero; cleared if nonzero.
AZ
• is cleared.
AN
