E1: set; E2:reset; Q: output
Set: Logic "1" at the set input will set output Q to logic "1".
Store: If a logic "0" is present at the S input, output Q remains unchanged.
Reset: If the R input is set to logic "1", output Q is set to logic "0".
Off: If both inputs are set to logic "1", output Q will be logic "0".

E1: clock input T; Q: output
The T flip-flop changes its output state with each positive clock edge at input 1 (clock
pulse input T). In all other signal states of the clock input (static logic "0" or logic "1"
or negative clock edge), the output signal remains unchanged.
Note: Input 2 is deactivated in this configuration. A parameterization of input
2 via the corresponding parameters will be have no effect for this rea-
son.
