Implementations

source

impl R

source

pub fn alrawf(&self) -> ALRAWF_R

Bit 0 - Alarm A write flag This bit is set by hardware when Alarm A values can be changed, after the ALRAE bit has been set to 0 in RTC_CR. It is cleared by hardware in initialization mode.

source

pub fn alrbwf(&self) -> ALRAWF_R

Bit 1 - Alarm B write flag This bit is set by hardware when Alarm B values can be changed, after the ALRBE bit has been set to 0 in RTC_CR. It is cleared by hardware in initialization mode.

source

pub fn wutwf(&self) -> WUTWF_R

Bit 2 - Wakeup timer write flag This bit is set by hardware up to 2 RTCCLK cycles after the WUTE bit has been set to 0 in RTC_CR, and is cleared up to 2 RTCCLK cycles after the WUTE bit has been set to 1. The wakeup timer values can be changed when WUTE bit is cleared and WUTWF is set.

source

pub fn shpf(&self) -> SHPF_R

Bit 3 - Shift operation pending This flag is set by hardware as soon as a shift operation is initiated by a write to the RTC_SHIFTR register. It is cleared by hardware when the corresponding shift operation has been executed. Writing to the SHPF bit has no effect.

source

pub fn inits(&self) -> INITS_R

Bit 4 - Initialization status flag This bit is set by hardware when the calendar year field is different from 0 (Backup domain reset state).

source

pub fn rsf(&self) -> RSF_R

Bit 5 - Registers synchronization flag This bit is set by hardware each time the calendar registers are copied into the shadow registers (RTC_SSRx, RTC_TRx and RTC_DRx). This bit is cleared by hardware in initialization mode, while a shift operation is pending (SHPF=1), or when in bypass shadow register mode (BYPSHAD=1). This bit can also be cleared by software. It is cleared either by software or by hardware in initialization mode.

source

pub fn initf(&self) -> INITF_R

Bit 6 - Initialization flag When this bit is set to 1, the RTC is in initialization state, and the time, date and prescaler registers can be updated.

source

pub fn init(&self) -> INIT_R

Bit 7 - Initialization mode

source

pub fn alraf(&self) -> ALRAF_R

Bit 8 - Alarm A flag This flag is set by hardware when the time/date registers (RTC_TR and RTC_DR) match the Alarm A register (RTC_ALRMAR). This flag is cleared by software by writing 0.

source

pub fn alrbf(&self) -> ALRBF_R

Bit 9 - Alarm B flag This flag is set by hardware when the time/date registers (RTC_TR and RTC_DR) match the Alarm B register (RTC_ALRMBR). This flag is cleared by software by writing 0.

source

pub fn wutf(&self) -> WUTF_R

Bit 10 - Wakeup timer flag This flag is set by hardware when the wakeup auto-reload counter reaches 0. This flag is cleared by software by writing 0. This flag must be cleared by software at least 1.5 RTCCLK periods before WUTF is set to 1 again.

source

pub fn tsf(&self) -> TSF_R

Bit 11 - Time-stamp flag This flag is set by hardware when a time-stamp event occurs. This flag is cleared by software by writing 0.

source

pub fn tsovf(&self) -> TSOVF_R

Bit 12 - Time-stamp overflow flag This flag is set by hardware when a time-stamp event occurs while TSF is already set. This flag is cleared by software by writing 0. It is recommended to check and then clear TSOVF only after clearing the TSF bit. Otherwise, an overflow might not be noticed if a time-stamp event occurs immediately before the TSF bit is cleared.

source

pub fn tamp1f(&self) -> TAMP1F_R

Bit 13 - RTC_TAMP1 detection flag This flag is set by hardware when a tamper detection event is detected on the RTC_TAMP1 input. It is cleared by software writing 0

source

pub fn tamp2f(&self) -> TAMP1F_R

Bit 14 - RTC_TAMP2 detection flag This flag is set by hardware when a tamper detection event is detected on the RTC_TAMP2 input. It is cleared by software writing 0

source

pub fn tamp3f(&self) -> TAMP1F_R

Bit 15 - RTC_TAMP3 detection flag This flag is set by hardware when a tamper detection event is detected on the RTC_TAMP3 input. It is cleared by software writing 0

source

pub fn recalpf(&self) -> RECALPF_R

Bit 16 - Recalibration pending Flag The RECALPF status flag is automatically set to 1 when software writes to the RTC_CALR register, indicating that the RTC_CALR register is blocked. When the new calibration settings are taken into account, this bit returns to 0. Refer to Re-calibration on-the-fly.
