       Type: Subroutine

    Summary: Calculate (A P) = |A| * Q
    Context: See this subroutine in context in the source code
 References: No direct references to this subroutine in this source file


 Do the following multiplication of a sign-magnitude 8-bit number P with an
 unsigned number Q:

   (A P) = |A| * Q

\
\AND #%01111111         \ Clear the sign bit in P, so P = |A|
\STA P
\
\                       \ Fall through into MULTU to calculate:
\                       \
\                       \   (A P) = P * Q
\                       \         = |A| * Q
