Instructions for Use

1. Power Supply:

   • Connect the VDD pin to the positive supply voltage (2.95 V to 5.5 V).
   • Connect the VSS pin to the ground.

2. Clock Configuration:

   • The internal high-speed clock (HSI) is enabled by default at 16 MHz.
   • For external clock sources, configure the appropriate clock control registers.

3. Programming:

   • Use an ST-LINK or similar programmer to program the device via the ICSP interface.
   • Ensure the programming voltage (VPP) is applied correctly if using an external programmer.

4. Reset:

   • The NRST pin can be used to reset the microcontroller.
   • A pull-up resistor is recommended on the NRST pin.

5. Low Power Modes:

   • Enter low power modes using the appropriate control registers.
   • Use the WFI (Wait For Interrupt) or WFE (Wait For Event) instructions to manage power consumption.

6. Analog-to-Digital Conversion:

   • Configure the ADC peripheral using the ADC control registers.
   • Use the ADC conversion complete interrupt to handle data.

7. Timers:

   • Configure the timers using the TIMx control registers.
   • Set up timer interrupts for periodic events or PWM generation.

8. Watchdog Timer:

   • Enable the watchdog timer to ensure the microcontroller resets in case of a software fault.
   • Feed the watchdog timer periodically to prevent an unintended reset.

9. Brownout Detection:

   • Enable brownout detection to reset the microcontroller if the supply voltage drops below a threshold.

10. GPIO Configuration:

    • Configure the GPIO pins as input, output, or alternate functions using the GPIO control registers.
    • Use internal pull-up or pull-down resistors as needed.
