Difference between I/O Refreshing in Customizable
Counter Units and That in Other Special I/O Units
The following describes the difference between I/O refreshing in Customiz-
able Counter Units and that in other Special I/O Units. Please note that the
time it takes to update data on both sides when a CPU Unit shares data with a
Customizable Counter Unit will significantly affect system operation.

Sets the first word address for output words in the CPU
Unit to 300 (BCD).
