Instructions for Use

1. Power Supply:

   • Connect the VCC pin to the positive supply (2.0 V to 5.5 V).
   • Connect the GND pin to the ground.

2. Clock Configuration:

   • Use an external crystal or oscillator connected to the XTAL1 and XTAL2 pins for clock generation.
   • Alternatively, use an internal RC oscillator by configuring the appropriate fuses.

3. Program Memory:

   • The device comes with 2 KB of ROM pre-programmed with factory-default code.
   • For custom programming, use an appropriate programmer compatible with the Z84C00 series.

4. Data Memory:

   • Access the 128 bytes of RAM for data storage and manipulation during program execution.

5. I/O Ports:

   • Configure the I/O ports (P0, P1, P2) as input or output using the port control registers.
   • Use the internal pull-up resistors for input pins if necessary.

6. Interrupts:

   • Enable and configure interrupts for INT0, INT1, T0, T1, and UART using the interrupt enable and priority registers.

7. Timers/Counters:

   • Initialize and control the 8-bit timers (T0, T1) for timing and counting functions.
   • Set up the prescaler and mode of operation as required.

8. Serial Communication:

   • Configure the UART for serial communication by setting the baud rate, data format, and other parameters.
   • Use the TXD and RXD pins for data transmission and reception.

9. Watchdog Timer:

   • Enable the watchdog timer to prevent system lockup by writing to the watchdog control register.
   • Clear the watchdog timer periodically to avoid a reset.

10. Power Management:

    • Enter low-power modes (Idle, Power Down, Power Save) to reduce power consumption when not actively processing.
    • Use the appropriate sleep and wake-up mechanisms to manage power efficiently.

11. Reset:

    • Ensure proper reset conditions by connecting the RST pin to a suitable reset circuit.
    • Use the watchdog timer or external reset signals to initiate a reset when necessary.
