In simulink, how to generate a square wave using an external source as frequency?

I want to generate a square wave where frequency is coming from an external source. In simulink square wave block, frequency parameter is hard coded.

you can use a normal Pulse generator block in Simulink and use set_param command to set any of the parameters like Amplitude, Period, PulseWidth, PhaseDelay, SampleTime etc.

set_param('Pulse Generator Block','Period',12);
