/*
DESCRIPTION
This is the WRS-supplied configuration module for the VxWorks 
dec21x40End (dc) END driver.  It performs the dynamic parameterization 
of the dec21x40End driver.  This technique of 'just-in-time' 
parameterization allows driver parameter values to be declared as 
any other defined constants rather than as static strings.
