[ Operation ]

src
[ Function ]
• This instruction multiplies src and dest together not including the sign bits and stores the result in dest .
• If you selected (.B) for the size specifier (.size), src and dest both are operated on in 8 bits and the
result is stored in 16 bits. If you specified an A0 or A1 for either src or dest , operation is performed on
the 8 low-order bits of A0 or A1.
• If you selected (.W) for the size specifier (.size), src and dest both are operated on in 16 bits and the
result is stored in 32 bits. If you specified R0, R1, or A0 for dest , the result is stored in R2R0, R3R1, or
A1A0 accordingly.
