Power control register (PWR_CR)
Bit 8 DBP: Disable backup domain write protection.
In reset state, the RTC and backup registers are protected against parasitic write access.
This bit must be set to enable write access to these registers.
0: Access to RTC and Backup registers disabled
1: Access to RTC and Backup registers enabled
Note: If the HSE divided by 128 is used as the RTC clock, this bit must remain set to 1.
