Valid Frame. Indicates whether a valid frame has received.
´0´: Received frame is invalid.
´1´: Received frame is valid.
Reserved
CRC compare check. Indicates whether a CRC check is failed or not.
´0´: CRC error check failed on the received frame.
´1´: Received frame is free of CRC errors.
Received message aborted. CMD message abortion is declared. The receive message
was aborted by the HOST. A sequence of 7 consecutive ´1´ was detected before closing
the flag. Note that ACK message and therefore RAB will not be send before destination
address was received.
´0´: Data reception is in progress.
´0´: Data reception has been aborted.
