  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?
  Scenario/Summary This week's lab covers two
areas, conversion of digital HCS12 signals to an
analog format, and the use of a Serial Peripheral
Interface (SPI) to transfer data, and commands
between the HCS12, and the DAC peripheral.
