6.3.21
Description: Subtracts the contents of the Sy operand from the Sx operand and stores the result in
the Du operand. The contents of the top word of the Se and Sf operands are multiplied as signed
and the result stored in the Dg operand. These two processes are executed simultaneously in
parallel.
The DC bit of the DSR register is updated according to the results of the ALU operation and the
specifications for the CS bits. The N, Z, V, and GT bits of the DSR register are also updated
according to the results of the ALU operation.
