Note:
(*) : LRXDL & LTXDL updated by Rx Response or Tx Response task
• The user initializes LTXDL field before setting the Tx Response command,
• After setting the Tx Response command, LRXDL is reset by hardware,
• LTXDL will remain unchanged during Tx (during busy signal),
• LRXDL will count the number of transmitted bytes (during busy signal),
• If an error occurs, Tx stops, the corresponding error flag is set and LRXDL will give the
• If no error occurs, LTXOK is set after the transmission of the CHECKSUM, LTXDL will be
• The UART mode forces LRXDL and LTXDL to 0 and disables the writing in LINDLR
• Note that after reset, LRXDL and LTXDL are also forced to 0.

Information on response (ex: error on byte) is only available at the end of the serializa-
tion/de-serialization of the byte.
