Controller Status File
The status file lets you monitor how your operating system works and lets you direct
how you want it to work. This is done by using the status file to set up control bits
and monitor both hardware and programming device faults and other status
information.
Note Do not write to reserved words in the status file. If you intend writing to status file
data, it is imperative that you first understand the function fully.
