2.2.39 (1) MULXU (B)
MULXU (MULtiply eXtend as Unsigned)
Operation
Rd
Assembly-Language Format
MULXU.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) 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
Available Registers
Rd: R0 to R7, E0 to E7
Rs: R0L to R7L, R0H to R7H
