<p class="MsoNormal"><span class="hcp2">The Logic
Display gives the ability to write customised text out to the front panel
LCD display. When the ‘Write’ input transitions to the high state the
text configured in the properties will be written to the display and the
output of the Logic Display will go high.</span></p>
<p class="MsoNormal" style="mso-ansi-language: EN-GB;">If configured by
the properties (‘Clear on Reset’), the ‘Reset’ input can be used to clear
the customised text from the front panel LCD. When the ‘Reset’ input is
high the Logic Display output will be driven low.</p>
<p class="MsoNormal" style="mso-ansi-language: EN-GB;">If there are more
than one of the Logic Display objects in the design, the object which
is triggered last will take control of the display.  The output of
any previously triggered Logic Display Object will remain high until it
either reaches its timeout or its Reset input is taken high.</p>

go low.</span></p>
