Label the following statements as TRUE or FALSE, and explain why.

a) As much processing as possible should be done within an interrupt service routine, rather than main()

b) One of PIC24 peripherals is a successive approximation ADC

c) One of PIC24 peripherals is a flash DAC

d) PIC24 can generate any frequency up to 1,000,000 Hz as SPI clock

e) Timer 2 in PIC24 cannot generate interrupts

Answer the following questions:

1) A PIC24 system has a 10-bit DAC attached to it with Vref=3.0V. If the PIC24 sends the 10-bit value 0x123 to the DAC, what is the output voltage from the DAC?

2) Assume a 4-bit successive approximation analog-to-digital converter (ADC) with Vref=5.0 volts. Assuming Vin=3.50 volts, show the operation of the ADC for each bitof the analog-to-digital conversion.
