Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_DD) is within the specified range of 1.8 to 3.6V.
   • Connect a stable power source to the V_DD and GND pins.

2. Clock Configuration:

   • The internal high-speed oscillator (HSI) is factory-trimmed to 16 MHz. It can be used directly or bypassed if an external clock source is preferred.
   • For precise timing, an external crystal or ceramic resonator can be connected to the OSC_IN and OSC_OUT pins.

3. GPIO Configuration:

   • Configure the GPIO pins as input, output, or alternate functions using the appropriate registers.
   • Use the internal pull-up or pull-down resistors for stable operation.

4. ADC and DAC:

   • Initialize the ADC and DAC modules by configuring the respective control registers.
   • Use the ADC to convert analog signals to digital values and the DAC to generate analog voltages from digital values.

5. Timers:

   • Set up the timers for various tasks such as generating PWM signals, measuring time intervals, or creating delays.
   • Use the timer interrupts to handle periodic events.

6. Communication Interfaces:

   • Initialize the UART, SPI, I²C, and I²S interfaces by configuring the corresponding registers.
   • Use these interfaces to communicate with other devices or peripherals.

7. Power Management:

   • Utilize the power-down and standby modes to reduce power consumption when the microcontroller is not actively processing data.
   • Implement the watchdog timers to ensure the system remains operational and resets in case of a fault.

8. Debugging:

   • Connect a debugger to the SWD interface for programming and debugging the microcontroller.
   • Use the debug interface to set breakpoints, inspect variables, and step through the code.
