Interrupt event

Variants§

TXFT = 134_217_728

TXFIFO reaches the threshold

RXFT = 67_108_864

This bit is set by hardware when the threshold programmed in RXFTCFG in USART_CR3 register is reached.

RXFF = 16_777_216

RXFIFO full

TXFE = 8_388_608

TXFIFO empty

BUSY = 65_536

Active when a communication is ongoing on the RX line

RTOF = 2_048

Receiver timeout.This bit is set by hardware when the timeout value, programmed in the RTOR register has lapsed, without any communication.

Txe = 128

Transmit data register empty. New data can be sent

TC = 64

Transmission Complete. The last data written in the USART_TDR has been transmitted out of the shift register.

Rxne = 32

New data has been received

Idle = 16

Idle line state detected

ORE = 8

Overrun error

NE = 4

Noise detection flag

FE = 2

Framing error

PE = 1

Parity error
