In the EKG waveform shown in Figure 11.79, there are long periods of constant value together with short periods of rapidly changing values. Notice that the data points in this figure are placed at uneven time intervals to match the various phases of this signal. Implement software that generates this waveform using uneven time output compare interrupts. In particular, create ROM-based tables that store the nine or ten points and use the DAC8043 12-bit DAC to create the periodic waveform.
