Describe “Indexed Register Indirect + offset” addressing mode with example?
An index register is used with a constant offset in this addressing mode. The value contained in the index
register is added with the constant offset to get the effective address. For example “mov [si+300], ax” moves
the word contained in AX to the offset attained by adding 300 to SI in the current data segment and the
instruction “mov [di+300], al” moves the byte contained in AL to the offset attained by adding 300 to DI in the current data segment.
