This error is generated in master of slave node configuration, when the USART expects a response from another node (NACT = SUBSCRIBE) but no valid message appears on the bus within the time given by the maximum length of the message frame, tFrame_Maximum (see Frame Slot Mode). This error is disabled if the USART does not expect any message (NACT = PUBLISH or NACT = IGNORE).
This error is reported by flag US_CSR.LINSNRE.
