Register 4 contains the update period for reading the resolver
position. Each count in this register is equivalent to 500
microseconds. The update period may range from 500 microseconds
to 32.7675 seconds. Refer to figure 4.3.

4.2 Local I/O Definition
Before any application program can be written, it is necessary to
configure, or set, the definitions of systemĆwide variables, i.e. those
that must be globally accessible to all tasks. This section describes
how to configure the input module when it is located in the same rack
as the processor module that is referencingit. Refer to figure 4.4.
