Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (2.0 to 5.5V).
   • Use a stable power source to avoid brown-out conditions.

2. Clock Configuration:

   • Connect an external crystal or oscillator if required.
   • Configure the internal clock settings via software to match your application needs.

3. Pin Configuration:

   • Refer to the pinout diagram in the datasheet for correct connections.
   • Configure I/O pins as inputs or outputs using the appropriate register settings.

4. Memory Management:

   • Write and read data from flash memory and EEPROM using the provided library functions.
   • Ensure proper write cycles and timing for non-volatile memory operations.

5. ADC Usage:

   • Initialize the ADC module and configure the channels and resolution.
   • Read analog values by triggering the ADC conversion and reading the results.

6. Timer Setup:

   • Set up the timers for various applications such as delays, PWM generation, and event counting.
   • Use interrupts to handle timer events efficiently.

7. Communication Interfaces:

   • Initialize UART, SPI, or I2C interfaces with the desired baud rates and protocols.
   • Implement communication routines to send and receive data.

8. Low Power Modes:

   • Enter sleep, idle, or power-down modes to reduce power consumption.
   • Use wake-up sources to resume operation when necessary.

9. Watchdog Timer:

   • Enable the watchdog timer to reset the microcontroller in case of a system hang.
   • Periodically refresh the watchdog timer to prevent unintended resets.

10. Programming:

    • Use a suitable development environment and programmer to upload code to the microcontroller.
    • Follow the programming guidelines in the datasheet to ensure successful firmware updates.
