6.3.2
Description: Adds the contents of the Sx and Sy operands and stores the result in the Dz operand.
When conditions are specified for DCT and DCF, the instruction is executed when those
conditions are TRUE. When they are FALSE, the instruction is not executed.
When conditions are not specified, the DC bit of the DSR register is updated according to the
specifications for the CS bits. The N, Z, V, and GT bits of the DSR register are also updated. If
conditions are specified, the DC, N, Z, V, and GT bits are not updated even is the conditions were
true and the instruction was executed.
