Why does the signal generator produce a triangle wave when I set the waveform value to 6 ?

When I use the waveform generator with simulink I get drop down list that allows sine, square, sawtooth, and random as choices. But if I attach a controldesk numeric input to the waveform input for the signal generator I found that a value of 6 will produce a triangle wave. Does anyone know where this "feature" might be documented ? -Phil

It looks you are using a third party product on top of Simulink. In case the community here is unable to help, you should consider contacting the developers of that product.
