4 o add source1, source2, dest
5 ----------------------------
7 Add source1 and source2, stores the result in dest.
9 Source1 and source2 can be either, immediate values or a register. Dest
12 o cmp source1, source2
13 ----------------------
15 Compare source1 and source2 and update PSW register accordingly. If source1
16 is lesser than source2, LE=1; if source1 equals source2 EQ=1; if source1
17 is greater than source2 GR=1.
19 Source1 can be either, a register or an immediate value. Source2 must
25 Stop processor execution.
30 Store dest in PC register, causing execution to continue from that address.
32 Dest can be either, a register or an immediate value.
37 Read the contents of the memory location specified by source1 into dest.
39 Source1 can be a register or an immediate. Dest must be a register.
44 Write source1 into memory location specified by dest.
46 Source1 must be register. Dest can be a register or an immediate.
48 o sub source1, source2, dest
49 ----------------------------
51 Subtract source2 from source1 and store the result in dest.
53 Source1 can be either an immediate value or a register. Source2 and dest
