Instructions for Use

1. Power Supply Connection:

   • Connect Vcc to +5V and GND to the ground.

2. Clock Input:

   • Provide a stable clock signal to the XTAL input. The Z80-DART requires an external crystal or clock source for timing operations.

3. Data Bus Configuration:

   • Connect the data bus lines (D0-D7) to the system data bus for communication with the CPU.

4. Control Signals:

   • Connect control signals such as RD (Read), WR (Write), CS (Chip Select), and A0-A1 (Address lines) appropriately to interface with the microprocessor.

5. UART Configuration:

   • Configure UART settings including baud rate, parity, stop bits, and word length via software initialization routines.

6. Interrupt Handling:

   • Set up interrupt handling for receive and transmit events using the INT pin and appropriate interrupt service routines.

7. Testing:

   • After setup, perform loopback tests to ensure proper operation of both receiver and transmitter channels.

8. Documentation:

   • Refer to the detailed datasheet for specific register configurations and advanced features like baud rate generation.

For more detailed information, refer to the official Zilog datasheets and application notes.
