Bit 31:24 Reserved, must be kept at reset value.
Bit 23 PC15MODE: PC15 mode
0: PC15 is controlled by the GPIO configuration registers. Consequently PC15 is floating in
Standby mode.
1: PC15 is forced to push-pull output if LSE is disabled.
Bit 22 PC15VALUE: PC15 value
If the LSE is disabled and PC15MODE = 1, PC15VALUE configures the PC15 output data.
Bit 21 PC14MODE: PC14 mode
0: PC14 is controlled by the GPIO configuration registers. Consequently PC14 is floating in
Standby mode.
1: PC14 is forced to push-pull output if LSE is disabled.
Bit 20 PC14VALUE: PC14 value
If the LSE is disabled and PC14MODE = 1, PC14VALUE configures the PC14 output data.
Bit 19 PC13MODE: PC13 mode
0: PC13 is controlled by the GPIO configuration registers. Consequently PC13 is floating in
Standby mode.
1: PC13 is forced to push-pull output if all RTC alternate functions are disabled.
Bit 18 PC13VALUE: RTC_ALARM output type/PC13 value
If PC13 is used to output RTC_ALARM, PC13VALUE configures the output configuration:
0: RTC_ALARM is an open-drain output
1: RTC_ALARM is a push-pull output
If all RTC alternate functions are disabled and PC13MODE = 1, PC13VALUE configures the
PC13 output data.
Bits 17:16 Reserved, must be kept at reset value.
Bit 15 TAMPPUDIS: RTC_TAMPx pull-up disable
This bit determines if each of the RTC_TAMPx pins are pre-charged before each sample.
0: Precharge RTC_TAMPx pins before sampling (enable internal pull-up)
1: Disable precharge of RTC_TAMPx pins.
