Instructions for Use:

1. Power Supply:

   • Connect the Vcc pin to a stable 5V power supply.
   • Connect the GND pin to the ground.

2. Clock Configuration:

   • Connect an external crystal or oscillator to the XTAL1 and XTAL2 pins for clock generation.
   • Alternatively, use an internal RC oscillator if available.

3. Reset:

   • Apply a high signal to the RESET pin for at least 2 clock cycles to initialize the microcontroller.

4. I/O Configuration:

   • Configure the I/O ports using the appropriate register settings in your code.
   • Set the direction of each port (input or output) using the DDRx registers.

5. Program Loading:

   • Load the program into the internal ROM using a suitable programmer or in-circuit debugger.
   • Ensure the program starts at the correct address (usually 0x0000).

6. Interrupts:

   • Enable interrupts by setting the appropriate bits in the interrupt enable register (IER).
   • Write interrupt service routines (ISRs) for each interrupt source.

7. Low Power Mode:

   • Enter low power mode by setting the appropriate bits in the power control register (PCR).
   • Use the watchdog timer to wake up from low power mode if necessary.

8. Serial Communication:

   • Configure the SCI or SPI for serial communication by setting the appropriate registers.
   • Use the TX and RX pins for data transmission and reception.

9. Timer/Counter:

   • Initialize the timer/counters by setting the mode and prescaler values.
   • Enable the timer/counters and use the overflow or compare match interrupts as needed.

10. Watchdog Timer:

    • Enable the watchdog timer by setting the appropriate bits in the watchdog timer control register (WDTCON).
    • Periodically reset the watchdog timer to prevent a system reset.

11. Debugging:

    • Use an in-circuit debugger to step through the code, set breakpoints, and monitor variables.
    • Ensure the debugger is connected to the appropriate debug pins on the microcontroller.
