The inputs and outputs can have the state ’0’ or ’1’. ’0’ means there is no
voltage at the input, and ’1’ means that there is. But that is unlikely to be
new to you.
We introduced the connectors hi, lo and x in order to facilitate program
entry for you. ’hi’ has the fixed state ’1’, and ’lo” has the fixed state ’0’.
If you do not want to wire an input on a block, you use the ’x’ connector.
