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 RTO?

I've setup USART to interrupt on a timeout using:CR2.RTOENCR1.RTOIEAnd configured the timeout using:RTOR.RTOIt works great, really nice feature. The RTO timeouts are always measured from the last stopbit/character received. However, I need to support...
