Instructions for Use

1. Power Supply:

   • Ensure the supply voltage is within the operating range (1.8 V to 3.6 V).
   • Connect the VDD and VSS pins to the appropriate power and ground sources.

2. Clock Configuration:

   • Configure the internal or external clock source as required.
   • Set the clock speed to the desired value (up to 120 MHz).

3. Reset Pin:

   • Connect the reset pin (NRST) to a pull-up resistor and ensure it can be pulled low to reset the device.

4. Programming:

   • Use the SWD interface for programming and debugging.
   • Connect the SWDIO and SWCLK pins to the debugger/programmer.

5. I/O Configuration:

   • Configure the I/O pins as inputs or outputs using the appropriate register settings.
   • Enable pull-up or pull-down resistors if needed.

6. Analog Inputs:

   • Connect analog signals to the ADC input pins.
   • Configure the ADC channels and start conversions using the ADC control registers.

7. Digital Interfaces:

   • Initialize and configure the SPI, I2C, UART, and USB interfaces according to the application requirements.
   • Use the respective control and status registers to manage communication.

8. Timers:

   • Set up the timers for various timing and counting tasks.
   • Configure the timer prescaler, period, and interrupt settings.

9. Low Power Modes:

   • Enter low power modes (Sleep, Deep Sleep, Standby) to reduce power consumption.
   • Use the power control registers to manage the entry and exit from these modes.

10. Protection:

    • Monitor the brown-out detection and overcurrent protection features to ensure safe operation.
    • Implement software checks to handle faults and protect the device.

11. Debugging:

    • Use the SWD interface for real-time debugging.
    • Set breakpoints, inspect variables, and trace execution using a compatible debugger.
