Section 6 Instruction Descriptions
6.3.15
Description: Takes the OR of the top word of the Sx operand and the top word of the Sy operand,
stores the result in the top word of the Dz operand, and clears the bottom word of Dz with zeros.
When Dz is a register that has guard bits, the guard bits are also zeroed. 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.
Note: The bottom word of the destination register and the guard bits are ignored when the DC bit
