Documents Flashcards Grammar checker. Discuss the pin configurations and operations of the A clock generator. Start the first phase of designing a single-board based microcomputer system.
This phase involves making the basic connections of the microprocessor in minimum mode and interfacing the A clock generator.
This circuit provides the following basic functions or signals: The functions of these pins are briefly discussed in next paragraphs refer to the A data sheet for more details. The two AEN signal inputs are useful in system configurations which permit the processor to access two multi-master system busses. READY is cleared after the guaranteed hold time to the processor has been met. The crystal frequency is 3 times the desired processor clock frequency.
The input signal is a square generahor 3 times the frequency of the desired CLK output.

Its frequency is equal to 82844a of the crystal. The 82C84A provides a schmitt trigger input so that an RC connection can be used to establish the power-up reset of proper duration. Its timing characteristics are determined by RES.
Clock Generator The A can derive its basic operating frequency from one of two sources: The crystal frequency should be selected at three times the required CPU clock. The A generates three clock signals: The OSC has the same frequency as the crystal or the external frequency and can be used to test the clock generator or as and external frequency 32 Clock Generator A input to other A chips.
This requirement can be achieved using a simple RC circuit as will be explained later in this experiment. Clock Generator A 2.
Dummy Crystal Crystal 3. This phase involves two main tasks: The first task will be accomplished in this experiment, while the second part will be deviated to the next experiment.
The procedure to build the A interface circuit is summarized below: Get the required circuit components from the Library. Interface the crystal circuit to the A Section 4.
Interface the reset circuit to the A Section 4.
Add clock and reset terminals Section 4. Note that this frequency is just for simulation purposes in real implementation a crystal of 15M Hz is used. The purpose of these terminals is allow the clock signal and reset logic to be connected to the design sheet which will be added to our project in the next LAB experiment. Run the simulation and determine the frequency and duty cycle of the three clock outputs: Calculate the minimum reset time mathematically Section 4.
Measure the minimum reset time using analog analysis Section 4. This requirement can be achieved by using the reset circuit discussed above with properly selected values for the resistor and capacitor.
The reset time is determined by the capacitor charging timing which can be calculated using the following RC charging formula: Note that in order to perform the analog analysis, you need to disconnect the line from the RES of the A.
Click on the “Add Trace” button and then select the voltage probe signal Vc as illustrated in the figure. Modify “stop time” to ms and uncheck the “initial DC solution” box as illustrated in the figure. To complete the analog analysis click on the “Simulate Graph” button as shown in Figure 4. The analog analysis simulation shows that the capacitor charge will reach 2.
