Response Data Length

Field
The LIN response data length is the number of data fields (bytes) of the response excluding the
checksum.
The response data length can either be configured by the user or be defined automatically by
bits 4 and 5 of the Identifier (compatibility to LIN Specification 1.1). The user can choose
between these two modes by the DLM bit of the LIN Mode register (US_LINMR):
Table 33-15. Response Data Length if DLM = 1
• DLM = 0: the response data length is configured by the user via the DLC field of the LIN
• DLM = 1: the response data length is defined by the Identifier (IDCHR in US_LINIR)
Mode register (US_LINMR). The response data length is equal to (DLC + 1) bytes. DLC can
be programmed from 0 to 255, so the response can contain from 1 data byte up to 256 data
bytes.
according to the table below. The DLC field of the LIN Mode register (US_LINMR) is
discarded. The response can contain 2 or 4 or 8 data bytes.
