Notes: 1. ddddddd is the higher 7 bits of disp8.
2. dddddd is the higher 6 bits of disp8.
3. ddddddddddddddd is the higher 15 bits of disp16.
4. Only the lower half-word data is valid.
5. ddddddddddddddddddddd is the higher 21 bits of dip22.
6. dddddddd is the higher 8 bits of disp9.
7. The op code of this instruction uses the field of reg1 through the source register is shown as reg2 in the
above table. Therefore, the meaning of register specification for mnemonic description and op code is
different from that of the other instructions
rrr = regID specification
RRRRR = reg2 specification
