Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the range of 2.0V to 5.5V.
   • Connect the VSS pin to ground.

2. Clock Configuration:

   • The internal RC oscillator operates at 8 MHz by default. For precise timing, an external crystal can be connected.

3. I/O Ports:

   • Configure the I/O ports as inputs or outputs using the appropriate register settings.
   • Use pull-up or pull-down resistors as needed for input pins.

4. ADC Usage:

   • Select the desired ADC channel and configure the ADC control registers.
   • Start the conversion and read the result from the ADC data register.

5. Timers:

   • Initialize the timer by setting the prescaler and mode.
   • Enable the timer and use interrupts if required.

6. Communication Interfaces:

   • Configure the UART, SPI, and I2C interfaces by setting the baud rate, data format, and other parameters.
   • Use the respective registers to send and receive data.

7. Watchdog Timer:

   • Enable the watchdog timer and set the timeout period.
   • Service the watchdog timer to prevent resets.

8. Low Power Modes:

   • Enter sleep mode to reduce power consumption.
   • Use wake-up sources such as interrupts to resume operation.

9. Programming:

   • Use an in-circuit programmer to write code to the flash memory.
   • Follow the programming guidelines provided in the datasheet for correct operation.

10. Temperature Considerations:

    • Ensure the operating temperature is within -40°C to 85°C.
    • Store the device in a temperature range of -55°C to 150°C.
