<Description>
This instruction sets a specified bit in the destination operand to "1." The bit number can be
specified by 3-bit immediate data, or by the lower three-bits of an 8-bit general register. The
destination operand can be located in a general register or memory.
The specified bit is not tested before being cleared. The condition code flags are not altered.
