Coding Multiple Right-hand Instructions

50
The next and final example may at first appear very complicated but can be
coded using only two logic block instructions. The diagram appears as fol-
lows:
Block a
0000 0001
0010 0011
0100
Block b
The first logic block instruction is used to combine the execution conditions
resulting from blocks a and b, and the second one is to combine the execu-
tion condition of block c with the execution condition resulting from the nor-
mally closed condition assigned bit 0003. The rest of the diagram can be
coded with OR, AND, and AND NOT instructions. The logical flow for this
and the resulting code are shown below.
Block b
0010 0011
LD 0010
AND 0011
OR LD
LD
0100
AND
0003
0002

AND LD

If there is more than one right-hand instruction executed with the same ex-
ecution condition, they are coded consecutively following the last condition
