///Field `NE` reader - Noise detection flag This bit is set by hardware when noise is detected on a received frame. It is cleared by software, writing 1 to the NFCF bit in the USART_ICR register. Note: This bit does not generate an interrupt as it appears at the same time as the RXFNE bit which itself generates an interrupt. An interrupt is generated when the NE flag is set during multi buffer communication if the EIE bit is set. When the line is noise-free, the NE flag can be disabled by programming the ONEBIT bit to 1 to increase the USART tolerance to deviations (Refer to Tolerance of the USART receiver to clock deviation on page 2317).

Note: When this bit is set, the USART_RDR register content is not lost but the shift register is overwritten.

When TDN is equal to the number of data in the TXFIFO, the TC flag is set when TXFIFO is empty and TDN is reached. When TDN is greater than the number of data in the TXFIFO, TC remains cleared until the TXFIFO is filled again to reach the programmed number of data to be transferred. When TDN is less than the number of data in the TXFIFO, TC is set when TDN is reached even if the TXFIFO is not empty. An interrupt is generated if TCIE=1 in the USART_CR1 register.

Every write operation to the USART_TDR places the data in the TXFIFO. This flag remains set until the TXFIFO is full. When the TXFIFO is full, this flag is cleared indicating that data can not be written into the USART_TDR. An interrupt is generated if the TXFNFIE bit =1 in the USART_CR1 register. Note: The TXFNF is kept reset during the flush request until TXFIFO is empty. After sending the flush request (by setting TXFRQ bit), the flag TXFNF should be checked prior to writing in TXFIFO (TXFNF and TXFE is set at the same time). This bit is used during single buffer transmission.

In Smartcard mode, the timeout corresponds to the CWT or BWT timings. Note: If a time equal to the value programmed in RTOR register separates 2 characters, RTOF is not set. If this time exceeds this value + 2 sample times (2/16 or 2/8, depending on the oversampling method), RTOF flag is set. The counter counts even if RE = 0 but RTOF is set only when RE = 1.

When wakeup on IDLE mode is selected, this bit can only be set by software, writing 1 to the MMRQ bit in the USART_RQR register. Note: If the USART does not support the wakeup from Stop feature, this bit is reserved and kept at reset value. Refer to .
    #[inline(always)]
    pub fn rwu(&self) -> RWU_R {
        RWU_R::new(((self.bits >> 19) & 1) != 0)
    }
    ///Bit 20 - Wakeup from low-power mode flag This bit is set by hardware, when a wakeup event is detected. The event is defined by the WUS bitfield. It is cleared by software, writing a 1 to the WUCF in the USART_ICR register. An interrupt is generated if WUFIE=1 in the USART_CR3 register. Note: When UESM is cleared, WUF flag is also cleared. If the USART does not support the wakeup from Stop feature, this bit is reserved and kept at reset value. Refer to .

    pub fn wuf(&self) -> WUF_R {
        WUF_R::new(((self.bits >> 20) & 1) != 0)
    }
    ///Bit 21 - Transmit enable acknowledge flag This bit is set/reset by hardware, when the Transmit Enable value is taken into account by the USART. It can be used when an idle frame request is generated by writing TE=0, followed by TE=1 in the USART_CR1 register, in order to respect the TE=0 minimum period.
    #[inline(always)]
    pub fn teack(&self) -> TEACK_R {
        TEACK_R::new(((self.bits >> 21) & 1) != 0)
    }
    ///Bit 22 - Receive enable acknowledge flag This bit is set/reset by hardware, when the Receive Enable value is taken into account by the USART. It can be used to verify that the USART is ready for reception before entering low-power mode. Note: If the USART does not support the wakeup from Stop feature, this bit is reserved and kept at reset value. Refer to .

    pub fn reack(&self) -> REACK_R {
        REACK_R::new(((self.bits >> 22) & 1) != 0)
    }
    ///Bit 23 - TXFIFO Empty This bit is set by hardware when TXFIFO is Empty. When the TXFIFO contains at least one data, this flag is cleared. The TXFE flag can also be set by writing 1 to the bit TXFRQ (bit 4) in the USART_RQR register. An interrupt is generated if the TXFEIE bit =1 (bit 30) in the USART_CR1 register.
    #[inline(always)]
    pub fn txfe(&self) -> TXFE_R {
        TXFE_R::new(((self.bits >> 23) & 1) != 0)
    }
    ///Bit 24 - RXFIFO Full This bit is set by hardware when the number of received data corresponds to RXFIFO size + 1 (RXFIFO full + 1 data in the USART_RDR register. An interrupt is generated if the RXFFIE bit =1 in the USART_CR1 register.
    #[inline(always)]
    pub fn rxff(&self) -> RXFF_R {
        RXFF_R::new(((self.bits >> 24) & 1) != 0)
    }
    ///Bit 25 - Transmission complete before guard time flag This bit is set when the last data written in the USART_TDR has been transmitted correctly out of the shift register. It is set by hardware in Smartcard mode, if the transmission of a frame containing data is complete and if the smartcard did not send back any NACK. An interrupt is generated if TCBGTIE=1 in the USART_CR3 register. This bit is cleared by software, by writing 1 to the TCBGTCF in the USART_ICR register or by a write to the USART_TDR register. Note: If the USART does not support the Smartcard mode, this bit is reserved and kept at reset value. If the USART supports the Smartcard mode and the Smartcard mode is enabled, the TCBGT reset value is '1'. Refer to on page 2297.

    ///Bit 26 - RXFIFO threshold flag This bit is set by hardware when the threshold programmed in RXFTCFG in USART_CR3 register is reached. This means that there are (RXFTCFG1) data in the Receive FIFO and one data in the USART_RDR register. An interrupt is generated if the RXFTIE bit =1 (bit 27) in the USART_CR3 register. Note: When the RXFTCFG threshold is configured to '101', RXFT flag is set if 16 data are available i.e. 15 data in the RXFIFO and 1 data in the USART_RDR. Consequently, the 17th received data does not cause an overrun error. The overrun error occurs after receiving the 18th data.
