MULNWH.D – Multiply Word with Negated Halfword
Architecture revision:
Architecture revision1 and higher.
Description
Multiplies the word register with the halfword register specified and stores the negated result in
the destination register pair. The halfword register is selected as either the high or low part of Ry.
Since the most significant part of the product is stored, no overflow will occur.
Operation:
I.
Syntax:
I.
