I want to generate square wave audio signal and modulate width and amplitude, in BF592 or similler board. If anyone have any idea or sample code then please help with that.
What is the purpose of generating an audio square wave from the DSP and modulate it? What is your application exactly does? Using Timer or PWM peripherals available in the DSP you can generate desired square wave (so width modulation can be eliminated). You may use an external device/chip to do the amplitude modulation
