STM32F0x1 Reference Manual (RM0091 Rev 9) does not specify what the values of USART ISR TEACK and REACK bits mean when they are 0 or 1.

Compare to other bitfields, e.g., :RWU0: Receiver in active mode1: Receiver in mute modeThere is no such 0 or 1 specified for TEACK and REACK bits.Also, discussion in USART Transmitter and USART Receiver sections do not discuss this.Thanks

How to use USART RTO timeout?

I have a STM32L4xx series microcontroller. My goal is to use RTO in USART to issue a timeout, from the time a read was attempted (not only from the last stop bit). This is needed as its possible for nothing to be received. How do I acheive this using...
