APPENDIX E Instructions
■ Memory Store Instructions
*: Special register Rs: TBR, RP, USP, SSP, MDH, MDL
(Notes)
The assembler calculates and sets values in the o8 and o4 fields of hardware specifications as
follows:
Disp10/4 --> o8, disp9/2 --> o8, disp8 --> o8: Disp10, disp9, and disp8 are signed.
Udisp6/4 --> o4: Udisp6 is unsigned.
