See 140EHC20200 High Speed Counter Module, page 346 for counter timing
diagrams illustrating output on times.
The following table shows the I/O Map register assignments.
In this example, block moves are used to load the operating parameters into the
module. This requires pre-defined tables be established. Register values are in HEX
format.
