(T=Z; Z=Y; Y=X;) X = (<input ii> active) ? TRUE : FALSE
This instruction uses debounced inputs. Debounce adds a delay of 8 to 20mS to the input response, in order to reject contact bounce (chattering) in mechanical input switches. If you need a faster response you can use the InputF (fast input) instruction, but you will get no protection from contact bounce.
* This instruction can also use the Index Register by adding i in front of the instruction.
Dialect restriction: This instruction is not implemented on boards prior to dialect D=6
