"UART Interview Questions Part 9: What happens if UART buffer overflows #firmware UART Interview Questions Part 9: What happens if UART buffer overflows When the UART buffer overflows it means the incoming data is arriving faster than the CPU or DMA can read it. Once the buffer is full new incoming data cannot be stored. This leads to data loss as unread bytes are discarded or overwritten depending on the hardware. Most UART peripherals raise an overrun error flag (ORE) when this condition occurs. The software must check and clear this flag before communication can continue. If not handled"

"What is a framing error in UART #embeddedsystemstutorials UART Interview Questions Part 7: What is a framing error in UART A framing error occurs in UART communication when the receiver does not detect the expected stop bit at the correct time. This usually happens when the transmitting and receiving devices are not synchronized often due to mismatched baud rates noise or signal distortion. The receiver samples incoming bits based on the configured baud rate. If the sampling point drifts or the stop bit is missing the UART hardware flags a framing error. This indicates that the received data"
