2.2.38 (1) MULXS (B)
MULXS (MULtiply eXtend as Signed)
Operation
Rd
Assembly-Language Format
MULXS.B Rs, Rd
Operand Size
Byte
Description
This instruction multiplies the lower 8 bits of a 16-bit register Rd (destination operand) by the
contents of an 8-bit register Rs (source operand) as signed data and stores the result in the 16-bit
register Rd. If Rd is a general register, Rs can be the upper part (RdH) or lower part (RdL) of Rd.
The operation performed is 8-bit 8-bit
Available Registers
Rd: R0 to R7, E0 to E7
Rs: R0L to R7L, R0H to R7H
