PUT : PUT the specified value into a Special Register

This instruction reads the contents of the first source register then writes it into the Special Register area. The index of this Special Register is specified by the last operand (the second register field or the optional immediate field).

This instruction is the reverse of the GET instruction.

Because of the rule that "the destination register is the last in the line", PUT it is the only instruction needing the FORM_RI form.
