EXTZL

Operation

Zero-extends the selected source width to a longword EA destination.

Assembler Syntax

EXTZL.B Rn(s), <ea>(e)

Zero-extends the source operand from the instruction size to long size and stores the four-byte result to an EA destination. The low source-size bytes are copied into the result, and the remaining high result bits are filled with zero. EXTZL has no Rn destination form; use MOV.B or MOV.W for a zero-extended Rn result.
