Latching button
Latching button input elements can be used to visualize and enter binary values with
the use of a checkbox and checkmark. Two different colors can be used based on a
Boolean value. To configure this type of element, you will need to select a bit oper-
and (marker bit 1 in the example above).
To enter input mode, press the <ALT> button at runtime or during the simulation. You
will then be able to use the checkbox by pressing the P2 or P4 button, and the binary
value will switch between 0 and 1 accordingly.
