Field RTOEN
reader - Receiver timeout enable This bit is set and cleared by software. When this feature is enabled, the RTOF flag in the USART_ISR register is set if the RX line is idle (no reception) for the duration programmed in the RTOR (receiver timeout register). Note: If the USART does not support the Receiver timeout feature, this bit is reserved and must be kept at reset value. Refer to .
