1. Give three examples each of internal and
external peripheral devices as referenced to the
HCS12 microcontroller and not an entire PC. (2
points)2. Given the requirements of each
signals destination must match the capabilities
of the signals source, name some of the
electrical signal parameters that must be
considered when designing an interface between
two different hardware components. (2 points)

1. Determine the conversion time for an ADC0804
(8-bit), where 66 clocks per bit are required, if
its clock frequency is 50 kHz.2. If an 8-bit SAR
has Vref 10 V, what is the binary value for an
input voltage of 7.28 V?3. What is the percent
error for the binary answer found in Problem 2?

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.
