Section 2 Instruction Descriptions
MULXS (MULtiply eXtend as Signed)
MULXS.W Rs, ERd
This instruction multiplies the lower 16 bits of a 32-bit register ERd (destination operand) by the
contents of a 16-bit register Rs (source operand) as signed data and stores the result in the 32-bit
register ERd. Rs can be the upper part (Ed) or lower part (Rd) of ERd. The operation performed is
ERd: ER0 to ER7
Operand Format and Number of States Required for Execution
Note: * The number of states in the H8S/2000 CPU is 21.

R0 to R7, E0 to E7
A maximum of three additional states are required for execution of this instruction within three states
after execution of a MAC instruction. For example, if there is a one-state instruction (such as NOP)
between the MAC instruction and this instruction, this instruction will be two states longer.
The number of states may differ depending on the product. For details, refer to the relevant
microcontroller hardware manual of the product in question.
