This example shows how to write/read data to/from Backup data registers and demonstrates the Tamper detection feature. The associated software performs the following: Configures the Tamper pin to be active on low level and enable Tamper interrupt. Then all Backup data registers are programmed after that we check if the written data are correct. If yes a led connected to PC.06 is turned on, otherwise a led connected to PC.07 is turned on. Once a low level is applied on PC.13 pin (ANTI_TAMP) the Backup data registers are reset and the Tamper interrupt is generated. In the corresponding ISR we check if the Backup data registers are cleared, if yes a led connected to PC.08 is turned on otherwise a led connected to PC.09 is turned on. In this example the system is clocked by the HSE(8MHz).
