Instructions for Use

1. Power Supply:

   • Ensure the supply voltage is within the operating range of 1.65 V to 3.6 V.
   • Connect the VDD pin to a stable power source and the VSS pin to ground.

2. Clock Configuration:

   • Configure the internal or external clock source as per application requirements.
   • Use the System Configuration (SYSCFG) and Clock Control (RCC) registers to set up the clock tree.

3. Reset and Boot:

   • The device can be reset using the NRST pin.
   • After reset, the device starts executing code from the bootloader or user flash memory based on boot configuration.

4. Peripheral Setup:

   • Initialize required peripherals using the appropriate initialization functions provided in the HAL or Standard Peripheral Libraries.
   • Refer to the Reference Manual for detailed register configurations.

5. Power Management:

   • Utilize low-power modes such as Sleep, Stop, and Standby to minimize power consumption.
   • Manage transitions between these modes using the Power Control (PWR) peripheral.

6. Debugging:

   • Use SWD (Serial Wire Debug) interface for debugging via the PA13 (SWDIO) and PA14 (SWCLK) pins.
   • JTAG interface is also available but shares pins with other functions.

7. Programming:

   • Program the flash memory using an ST-LINK programmer/debugger or other compatible tools.
   • Follow the programming guidelines specified in the Programming Manual.

For detailed information, refer to the STM32L100R8T6 datasheet and reference manual available on the STMicroelectronics website.
