a. What is a device register?
b. What is a device data register?
c. What is a device status register?

(a)

Expert Solution
Check Mark
Program Plan Intro

To describe about a device register.

Explanation of Solution

Explanation:

Every device has an associated device register. A device register contains information about the logical address of the device. This address can be programmed manually or by the operating system. The information in the device register is used by the operating system or other equipment to find the respective device.

Example:

When a user connects a digital camera with the computer, the computer then interacts with the device register of the digital camera and uses the information in its device register to set up the digital camera.

A device register has two more associated registers namely device data register and device status register.

Program Plan Intro

To describe about a device data register.

Explanation of Solution

Explanation:

A device data register performs no actions but stores only data and other information. The other information is related to how much space is available to store the data. The device can read or write data to and from this device data register.

Using the space availability information contained in the device data register, it is easy to send or retrieve information to and from the device.

(c)

Expert Solution

Program Plan Intro

To describe about a device status register.

Explanation of Solution

Explanation:

As the name suggests, the device status register shows the status or mode of operation of the device. If the device is busy or faces some issue while performing a task, the respective message will be displayed by its device status register.

Example:

Consider a device1 that is busy. If other device2 wants to interact with device1, the device status register of device1 will show the message that the device is busy. On the other hand, if an error occurs with the operations being performed by device1, its device status register will show an error message.

Specifications: Part-2Part-2: DescriptionIn this part of the lab, we will illuminate two 7-segment displays. You will need to understand 2's Complement todetermine when the input 4-bit binary number corresponds to a negative or positive number. To understand how anLED display works in Digital, please refer to the playWithLED_Display.dig file provided. You should play withdifferent input combinations to see how it influences the LED Display value. In the screenshot below, note how I wasable to generate the display of “3” on the Hex display by lighting up only certain input wires to the unit. Here is a picture of how the different segments light up to produce the different displays: Note in the picture above that we showed displays only from 0-8 since in 4-bit 2s complement representation, 8 is thelargest modulus value you can represent (the range of integers would be -8 to +7).Your circuit in Part-2 must accept a 4-bit 2's complement input {in3, in2, in1, in0} where in3 is the most…
