Main program.
Returns the last stored variable data, if found, which correspond to the passed virtual address
Verify if specified page is fully erased.
Writes/updates variable data in EEPROM.
Restore the pages to a known good state in case of page's status corruption after a power loss.
This function is executed in case of error occurrence.
Verify if active page is full and Writes variable in EEPROM.
Erases PAGE and PAGE1 and writes VALID_PAGE header to PAGE
Find valid Page for write or read operation
Transfers last updated variables data from the full Page to an empty one.
System Clock Configuration The system Clock is configured as follow : System Clock source = PLL (HSE) SYSCLK(Hz) = 84000000 HCLK(Hz) = 84000000 AHB Prescaler = 1 APB1 Prescaler = 2 APB2 Prescaler = 1 HSE Frequency(Hz) = 8000000 PLL_M = 8 PLL_N = 336 PLL_P = 4 PLL_Q = 7 VDD(V) = 3.3 Main regulator output voltage = Scale2 mode Flash Latency(WS) = 2

Summary
Internal High Speed oscillator (HSI) value. This value is used by the RCC HAL module to compute the system frequency (when HSI is used as system clock source, directly or through the PLL). Value of the Internal oscillator in Hz
Adjust the value of External High Speed oscillator (HSE) used in your application. This value is used by the RCC HAL module to compute the system frequency (when HSE is used as system clock source, directly or through the PLL). Value of the External oscillator in Hz
Miscellaneous Configuration *********************** Vector Table base offset field. This value must be a multiple of 0x200.
