Instructions for ST7FMC2S4T6

1. Power Supply Configuration:

   • Ensure the supply voltage is within the operating range (1.8V to 5.5V).
   • Connect decoupling capacitors close to the power supply pins to reduce noise.

2. Clock Setup:

   • Configure the internal or external oscillator as per application requirements.
   • Use the clock control registers to set the system clock frequency up to 24 MHz.

3. Flash Programming:

   • Program the flash memory using an in-circuit programmer compatible with the ST7 series.
   • Follow the programming protocol specified in the device datasheet.

4. Peripheral Initialization:

   • Initialize ADC, timers, and communication interfaces by configuring their respective control registers.
   • Set up interrupt handlers if using interrupts for peripherals.

5. Low Power Mode:

   • Enter low power modes by configuring the power control register.
   • Use the appropriate wake-up sources to exit from low power modes.

6. GPIO Configuration:

   • Configure GPIO pins as inputs, outputs, or alternate functions according to the pin function table.
   • Enable pull-up or pull-down resistors as needed.

7. Watchdog Timer:

   • Initialize and start the watchdog timer to prevent software lockups.
   • Service the watchdog periodically to prevent resets.

8. Calibration Data Usage:

   • Utilize the internal calibration data for accurate ADC conversions and other parameters that require calibration.
