8.3.7.9.4 Character Reception

When receiving a LON frame, the Receive Holding register (FLEX_US_RHR) is updated upon completed character reception and the RXRDY bit in the Status register rises. If a character is completed while the RXRDY bit is set, the OVRE (Overrun Error) bit is set. The LON preamble field is only used for synchronization, therefore only the Data and CRC fields are transmitted to the Receive Holding register (FLEX_US_RHR). See Sending a Frame.
