4.3.2 REGISTER DESCRIPTION
The Model 2190 uses registers to store configuration status. Some
of the registers control only one function, but some of them are called
bit mapped registers which control several functions in a single regis-
ter. The chart below identifies the codes, function, default, range and
units of the S-registers.
Register Descriptions (continued)
Register value may be stored in one of two user profiles with the
&W command.
