Description: Clears 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 Z bit of the DSR register is set to 1. The N, V, and GT bits are
cleared to 0. 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.
