Instructions for Use

1. Power Supply Connection:

   • Connect the Vcc pin to a stable 5V power supply.
   • Ensure GND is connected to the system ground.

2. Clock Input:

   • Provide a suitable clock signal to the CLK pin. The frequency should be chosen based on the desired baud rate.

3. UART Configuration:

   • Set up the control lines (CS, RD, WR) as per your system requirements.
   • Configure the data input/output pins (D0-D7) for communication.

4. Baud Rate Setting:

   • Adjust the baud rate using the BRG register and external clock frequency.

5. Interrupt Handling:

   • Monitor the interrupt output (INT) for asynchronous events.
   • Implement appropriate interrupt service routines in your application code.

6. Data Transmission and Reception:

   • Use the transmit (TD) and receive (RD) data lines for serial communication.
   • Ensure proper handshaking protocols if required.

7. Testing and Validation:

   • After setup, test the device with known data patterns to verify correct operation.
   • Check for any noise or interference that might affect performance.
