• 1. What are the four main functions of the HC12
  Timer unit?
• 2. Two input capture events occur at counts
  0x1037 and 0xFF20 of the free-running counter.
  How many counts (in decimal) have transpired
  between these two events?
• 3. What is the maximum time possible before the
  free-running counter overflows when the e MHz?

• 7. What is the duty cycle of a signal produced by
  the PWM when and ?
• a. 28.0 b. 29.8 c. 50.0 d. 72.0
• 8. What values are required for period and duty
  cycle to generate a 6.0 kHz, 95 duty cycle
  waveform using the PWM function? Assume e-clock
  frequency is 24 MHz.
• 9. What is the slowest clock signal that can be
  generated from the PWM output using the 16-bit
  counter mode with pre-scaling and scaling? Assume
  e-clock frequency is 24 MHz.
• 10. Write down the C statements needed to program
  PWM channel 0 to output a 12.5 kHz left-aligned
  wave with 30 duty cycle. Assume e-clock
  frequency is 24 MHz.
