• LRXDL and LTXDL fields are both hardware updated before setting LIDOK by decoding the
• Via the above mechanism, a length of 0 or >8 is not possible.
• The user initializes LRXDL field before setting the Rx Response command,
• After setting the Rx Response command, LTXDL is reset by hardware,
• LRXDL field will remain unchanged during Rx (during busy signal),
• LTXDL field will count the number of received bytes (during busy signal),
• If an error occurs, Rx stops, the corresponding error flag is set and LTXDL will give the
• If no error occurs, LRXOK is set after the reception of the CHECKSUM, LRXDL will be
