       Type: Subroutine
   Category: Maths (Arithmetic)
    Summary: Set P(1 0) = (A A)
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * MLS1 calls MU6


 In practice this is only called via a BEQ following an AND instruction, in
 which case A = 0, so this routine effectively does this:

   P(1 0) = 0


.MU6

 STA P+1                ; Set P(1 0) = (A A)
 STA P

 RTS                    ; Return from the subroutine
