The status flags required for data transfer is present in Interface circuit.

Explanation:
The status flags are used to indicate the status or condition of a particular operation or event. In the context of data transfer, these flags are used to indicate the status of the data being transferred. They can provide information such as whether the data transfer is complete or in progress, whether there are any errors or issues with the transfer, or any other relevant information.

The status flags required for data transfer are typically present in the interface circuit. The interface circuit acts as a bridge between the device and the device driver. It is responsible for facilitating the communication between the device and the computer system.

Role of Interface Circuit:
The interface circuit is designed to handle the specific requirements of the device and ensure smooth data transfer. It includes various components such as buffers, registers, and control logic that are used to control and monitor the data transfer process.

Key Points:
- The interface circuit is responsible for managing the data transfer between the device and the computer system.
- It includes various components such as buffers, registers, and control logic.
- The status flags required for data transfer are present in the interface circuit.
- These flags provide information about the status of the data transfer process, such as completion status, error detection, etc.

Conclusion:
In conclusion, the status flags required for data transfer are present in the interface circuit. The interface circuit plays a crucial role in managing the data transfer process and includes the necessary components to control and monitor the transfer.
