MULH = W × lit8; high 8 bits of unsigned product Bits affected: None Opcode: 0111 0010 kkkk kkkk Description: This instruction performs an unsigned multiply of
an 8-bit literal by the contents of W. The low 8 bits
of the product are written to W, and the high 8 bits
are   written   to   the   MULH   register.   The   data
memory location is left unchanged. Cycles: 1 Example: mulu  w,#0x75 This example multiplies the contents of W by the
literal 0x75 into W. The high byte of the result is
loaded into the MULH register, and the low byte is
loaded into W.
