LIN Errors
LIN Frame Handling
Identifier Parity Error (CSR.LINIPE)
Inconsistent Sync Field Error (CSR.LINISFE)
Master Node Configuration
Slave Not Responding Error (CSR.LINSNRE)
Checksum Error (CSR.LINCE)
Bit Error (CSR.LINBE)
Note:
If the Checksum is sent (CHKDIS=0):
If the Checksum is not sent (CHKDIS=1):
These error bits are cleared by writing a one to CSR.RSTSTA.
This error is generated if no valid message appears within the TFrame_Maximum time frame
slot, while the USART is expecting a response from another node (NACT=SUBSCRIBE).
This error is generated if the received checksum is wrong. This error can only be generated if the
checksum feature is enabled (CHKDIS=0).
This error is generated if the identifier parity is wrong. This error can only be generated if parity is
enabled (PARDIS=0).
This error is generated in slave mode if the Sync Field character received is not 0x55. Synchro-
nization procedure is aborted.
This error is generated if the value transmitted by the USART on Tx differs from the value sam-
pled on Rx. If a bit error is detected, the transmission is aborted at the next byte border.
The following procedure depends on the NACT setting:
• TFrame_Maximum = 1.4 x (THeader_Nominal + TResponse_Nominal + 1)
• TResponse_Nominal = 10 x (NData + 1)
• TFrame_Maximum = 1.4 x (34 + 10 x (DLC + 1 + 1) + 1)
• TFrame_Maximum = 77 + 14 x DLC
• TResponse_Nominal = 10 x NData
• TFrame_Maximum = 1.4 x (34 + 10 x (DLC + 1) + 1)
• TFrame_Maximum = 63 + 14 x DLC
• Write a one to CR.TXEN and CR.RXEN to enable both transmitter and receiver
• Select LIN mode and master node by writing to MR.MODE
• Configure the baud rate by writing to CD and FP in BRGR
• Configure the frame transfer by writing to NACT, PARDIS, CHKDIS, CHKTYPE, DLCM,
• Check that CSR.TXRDY is one
• Send the header by writing to LINIR.IDCHR
FSDIS, and DLC in LINMR
The term “+1” leads to an integer result for TFrame_Max (LIN Specification 1.3)
