BKP register map
BKP registers are mapped as 16-bit addressable registers as described in the table below:
BKP register map and reset values
Bit 8 TEF: Tamper event flag
Bit 2 TPIE: TAMPER pin interrupt enable
Bit 1 CTI: Clear tamper interrupt
Bit 0 CTE: Clear tamper event
Note: A Tamper event resets all the BKP_DRx registers. They are held in reset as long as the
Note: 1: A Tamper interrupt does not wake up the core from low-power modes.
This bit is set by hardware when a Tamper event is detected. It is cleared by writing 1 to the
CTE bit.
0: No Tamper event
1: A Tamper event occurred
0: Tamper interrupt disabled
1: Tamper interrupt enabled (the TPE bit must also be set in the BKP_CR register
This bit is write only, and is always read as 0.
0: No effect
1: Clear the Tamper interrupt and the TIF Tamper interrupt flag.
This bit is write only, and is always read as 0.
0: No effect
1: Reset the TEF Tamper event flag (and the Tamper detector)
TEF bit is set. If a write to the BKP_DRx registers is performed while this bit is set, the
value will not be stored.
2: This bit is reset only by a system reset and wakeup from Standby mode.
