ECET 340 Week 1 HomeWork 1

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 signal’s destination must match the capabilities of the signal’s source,” name some of the electrical signal parameters that must be considered when designing an interface between two different hardware components. (2 points)

3. Write down the instructions needed to program PORT A for pins PA7, PA4-PA0 as inputs and PA6-PA5 as outputs. Answer should be a valid C language statement. (2 points)

4. Write an instruction sequence to output the value $35 to PORT P. Use the C language only when writing your answer; – no assembly language. (2 points)

5. Write an instruction sequence to configure Port H for input, read in the current signal levels on the Port H pins, and store the value to a C variable called data1. Use the C language only when writing your answer, no assembly language. Also make sure to set the data direction register appropriately in your answer. (2 points)

6. Write a short program in C language which reads in the bits on port H, inverts the bits and adds 1 to the result, and then outputs the result onto port P. Be sure to include port initializations and variable declarations in your code. (2 points)

7. Using only Ports B, H, & J, (see Figure 1} write C code to read in the value from dip switch 1 (SW1) {all 8 bits}, invert the bits, and then display the results on the 8 LEDs driven by Port B (see Figure 3). When the value is a ‘1’, the LED is ON, and when it is a ‘0’, the LED is off. See how SW1 is connected to Port H (see Figure 2), and how the LEDs are connected to Port J (see Figure 3) (2 points)

8. What maximum current will be drawn from the 5V output of a peripheral device connected to an HCS12 input port? What input resistance does this represent? Please note the problem states connected to an HCS12 “input port”. (3 points)

9. Given an LED with a forward drop of 1.5V and an operating current of 10 mA, design the interface to the HCS12 showing your calculations. (3 points)

ECET 340 Week 1 iLab 1

1. To become familiar with Microcontroller MC9S12 parallel ports and how simple input and output devices are interfaced through them.
2. To learn how to program I/O instructions in C language.
3. To learn how to organize a program to read data from input ports, process the data, and display the result on a simple output device.

1. Where does program control transfer to when an interrupt occurs? +2 points

2. Which one of the following Interrupts has highest priority? +2 points

3. RAM Vector table addresses $3E52 belongs to which interrupt? +2 points

4. Before exiting an ISR, the programmer should use which command? +2 points

5. In which one of the following sequences is the stack pulled by rti? +3 points

6. Given the starting address for the TC0 Interrupt is to become $5000. Write the assembly instruction necessary to place this ISR address into the interrupt vector table and then unmask the interrupt (assembly only). +3 points

7. Write the C statements needed to place the address of an interrupt service routine that is to be called PortJ_handler into the vector address for the Port J interrupt and then unmask the interrupt. +3 points

8. Circle the interrupt below that will have highest priority after the statement ;is executed. +3 points
