Example:
MOV.L @(2*,R0),R1 ;Before execution (R0+8) = H'12345670
;After execution R1 = H'12345670
MOV.L R0,@(H'F,R1) ;Before execution R0 = H'FFFF7F80
;After execution (R1+60) = H'FFFF7F80
Note: * The assembler of Renesas Technology uses the value after scaling (×1, ×2, or ×4) as
the displacement (disp).
Possible Exceptions:
• Data TLB multiple-hit exception
• Slot illegal instruction exception
• Data TLB miss exception
• Data TLB protection violation exception
• Data address error
