NAME

       demux - Select one of several output pins by integer and/or or individual bits.

SYNOPSIS

       loadrt demux [count=N|names=name1[,name2...]] [personality=P1,P2,...]

DESCRIPTION

       This  component  creates a number of output bits defined by the "personality" command-line parameter. One
       of these bits will be set based on interpreting the bit-inputs as a binary number and then adding on  the
       integer  input.  Most  uses  will  use  only  one  or  the other, but it is possible to use the bits as a
       ""shift"" if required.  An optional operating mode is enabled by  setting  the  "bargraph"  parameter  to
       true,  in this case all bits up to the selected bit will be set, as might be required for an LED bargraph
       display.
