2) When the nesting structure is adopted
When using MC instructions inside MC instruction, increase the nest level "N" in turn in the way "N0 → N1 → N2
→ N3 → N4 → N5 → N6 → N7".
For returning from the nesting structure, reset the nest levels from the highest one in turn using MCR instruction in
the way "N7 → N6 → N5 → N4 → N3 → N2 → N1 → N0".
For example, if "MCR N5" is programmed without programming "MCR N6" and "MCR N7", the nest level is
returned to 5 immediately.
Available nest levels are from N0 to N7 (eight layers).

The bus line D is active while all of X000,
X002 and X004 are ON.
Level N1
The bus line returns to the status of the bus
line C by "MCR N2".
Level N0
The bus line returns to the status of the bus
line B by "MCR N1".
Initial status
The bus line returns to the initial status of the
bus line A by "MCR N0". Accordingly, Y005
