Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the specified range of 1.71 V to 3.6 V.
   • Connect the Vss (ground) pin to a stable ground reference.

2. Clock Configuration:

   • The internal high-speed RC oscillator (HSI) is enabled by default at 16 MHz.
   • For higher precision, an external crystal can be connected to the XTAL1 and XTAL2 pins.

3. Reset Pin:

   • The NRST pin is used for system reset. It should be pulled high to keep the device active.
   • A low signal on this pin will reset the microcontroller.

4. GPIO Configuration:

   • Configure GPIO pins as input or output using the appropriate register settings.
   • Enable pull-up or pull-down resistors if needed.

5. Communication Interfaces:

   • Initialize the communication interfaces (SPI, I2C, UART, USB) according to the application requirements.
   • Refer to the datasheet for specific register configurations and timing parameters.

6. Low Power Modes:

   • Enter low power modes (Sleep, Deep Sleep, Standby) to reduce power consumption.
   • Use the appropriate wake-up sources to exit these modes.

7. ADC and DAC:

   • Configure ADC channels for analog input measurements.
   • Set up DAC channels for analog output generation.

8. Timer Configuration:

   • Configure general-purpose timers for various timing and counting tasks.
   • Use the timer interrupt capabilities for event-driven operations.

9. Watchdog Timer:

   • Enable the watchdog timer to prevent system lock-ups.
   • Periodically refresh the watchdog timer to avoid a system reset.

10. Programming and Debugging:

    • Use an in-circuit debugger or programmer to upload firmware to the flash memory.
    • Utilize the SWD (Serial Wire Debug) interface for debugging purposes.

11. Handling Precautions:

    • Handle the microcontroller with care to avoid ESD damage.
    • Follow proper soldering techniques to ensure reliable connections.

For detailed information, refer to the official datasheet and application notes provided by the manufacturer.
