Table I.4 lists the complete output object references. Use the relative indexes from Table I.3 to
determine specific bit locations. Objects 8-83 are unique from other objects because the actual
port being mapped to is determined by the analog output object. This yields two ways in which
binary output objects can be operated: directly using indexes 0-7 and 84-1299 or by reference by
writing to analog output object 0 and binary output object 8-83 at the same time. The bits can
only be read using the analog output object to select the data to read.
