Section 6 Instruction Descriptions
6.3.13
Description: The contents of the top word of the Se and Sf operands are multiplied as signed and
the result stored in the Dg operand. The DC, N, Z, V, and GT bits of the DSR register are not
updated.
Note: Since PMULS performs fixed decimal point multiplication, the operation result will be
