Section 1-3
the five positions immediately to the right of the CPU Unit. For CJ1M CPU
Units, the CJ1W-CTL41-E Counter Unit must be in one of the three posi-
tions immediately to the right of the CJ1M CPU Unit. No external interrupt
tasks can be activated if the Unit is in any other position (i.e., 6th Unit po-
sition or further away from the CJ1-H CPU Unit, or 4th Unit position or fur-
ther away from the CJ1M CPU Unit), or if it is on a CJ-series Expansion
Rack.

If an IOWR- or IORD-instruction is used during operation, comparison will
stop during instruction execution. Care must be taken, therefore, with the
timing of executing instructions. (Refer to section
for de-
tails.)
