Universal synchronous asynchronous receiver transmitter (USART) UM0306
412/519
Bit 1
RWU: Receiver Wake-Up.
This bit determines if the USART is in mute mode or not. It is set and cleared by
software and can be cleared by hardware when a wake-up sequence is
recognized.
0: Receiver in active mode
1: Receiver in mute mode
Notes:
1: Before selecting Mute mode (by setting the RWU bit) the USART must first
receive a data byte, otherwise it cannot function in Mute mode with wake-up by Idle
line detection.
2: In Address Mark Detection Wake-Up configuration (WAKE bit=1) the RWU bit
cannot be modified by software while the RXNE bit is set.
Bit 0
SBK: Send Break.
This bit set is used to send break characters. It can be set and cleared by
software. It should be set by software, and will be reset by hardware during the
stop bit of break.
0: No break character is transmitted
1: Break character will be transmitted
