• If LTXDL[3..0]=0 only the CHECKSUM will be sent,
• If LRXDL[3..0]=0 the first byte received will be interpreted as the CHECKSUM,
• If LTXDL[3..0] or LRXDL[3..0] >8, values will be forced to 8 after the command setting and
• 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
