Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (2.7 V to 5.5 V).
   • Connect the Vcc and GND pins to a stable power source.

2. Clock Configuration:

   • Use the internal 4 MHz RC oscillator for basic applications.
   • For higher precision, connect an external crystal oscillator between the X1 and X2 pins.

3. I/O Configuration:

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

4. Timer Setup:

   • Initialize the timer/counter modules by setting the TCCR registers.
   • Use the timer overflow interrupt to generate periodic events.

5. Serial Communication:

   • Configure the UART, SPI, and I2C interfaces using the respective control registers.
   • Set the baud rate for UART communication using the UBRR register.

6. ADC Operation:

   • Select the analog input channel using the ADMUX register.
   • Start the conversion by setting the ADSC bit in the ADCSRA register.
   • Read the conversion result from the ADCL and ADCH registers.

7. Low-Power Modes:

   • Enter low-power modes by setting the appropriate bits in the MCUCR register.
   • Use the watchdog timer to wake up from sleep modes.

8. Interrupt Handling:

   • Enable global interrupts by setting the I bit in the SREG register.
   • Write interrupt service routines (ISRs) for specific interrupt sources.

9. Brownout Detection:

   • Enable brownout detection by setting the BOD bit in the MCUCR register.
   • The device will reset if the supply voltage drops below the threshold.

10. Reset:

    • The device can be reset using the external reset pin, power-on reset, brownout reset, or watchdog reset.
    • Ensure the reset pin is held high during normal operation to prevent accidental resets.
