Modes 1XXX primarily utilize TC132X DAC modes:
1. Mode1000: Generate a 100 Hz 32-step sine wave on the TC132X. Analyze
2. Mode1001: Send 000h and FFFh commands to generate a 100 Hz R-R output
3. Mode1010: Send 400h and BFFh commands to generate a 100 Hz output on the
4. Mode1011: DAC = SHDN, PIC = SLEEP. This mode demonstrates the
5. Mode1100: DAC = 200h and Read with PIC16F767 10b ADC, “broadcast on
