If Working Register Pair RR6 (R6 and R7) contains the value 404Ah,

Data Memory location

404Ah and 404Bh contain the values ABh and C3h

respectively, and Working Register R2 contains the value

22h, the follow-

ing statement loads the value ABh into Register 22h.

LDEI @R2, @RR6



Object Code: 83 26

Working Register Pair RR6 increments to 404Bh and Working Register

R2 increments to

23h. A second instruction loads the value C3h into Reg-

ister 23h:

LDEI @R2, @RR6



Object Code: 83 26

Working Register Pair RR6 increments to 404Ch and Working Register

R2 increments to

24h.

If Working Register R2 contains the value 22h, Register 22h contains the

value

ABh, Register 23h contains the value C3h, and Working Register

Pair R6 and R7 contains the value

404Ah, the following statement loads

the value

ABh into Data Memory location 404Ah:

LDEI @RR6, @R2



Object Code: 93 26

Working Register R2 increments to 23h and Working Register Pair RR6

increments to
