 Using this, can you translate these? 1. MAR:= PC;RD 2. MAR:=PC;

Using this, can you translate these?

1. MAR:= PC;RD

2. MAR:=PC; MBR:=AC; WR

3. IR:= MBR

4. TIR:= IR; GOTO 25

5. C:= A + B; IF Z GOTO 65

6. TIR := LSHIFT(IR + IR); IF N GOTO 0

7. AC := BAND(AC, AMASK)

This is what an expected answer looks like:

MBR:=AC; WR 3. IR:= MBR 4. TIR:= IR; GOTO 25 5. C:=
