Write a 68hc11 assembly language program which generation of the following waveforms connected to your DAC
i) Square wave
ii) Saw tooth waveform
iii) Sine wave
iv) User defined waveform - AM modulated waveform (fixed)
Note: You are required to write a functional modular program which will enable the user to select the different waveforms using the keyboard or for reduced marks an input/output box and produce the fastest, high quality waveform possible.
