xxERR Flags
LERR bit of the LINSIR register is an logical ‘OR’ of all the bits of LINERR register (see
tion 15.5.13 “Interrupts” on page
After each LIN error, the LIN controller stops its previous activity and returns to its withdrawal
mode (LCMD[2:0] = 000
Writing 1 in LERR of LINSIR register resets LERR bit and all the bits of the LINERR register.
• LBERR = LIN Bit ERRor.
• LCERR = LIN Checksum ERRor.
• LPERR = LIN Parity ERRor (identifier).
• LSERR = LIN Synchronization ERRor.
• LFERR = LIN Framing ERRor.
• LTOERR = LIN Time Out ERRor.
• LOVERR = LIN OVerrun ERRor.
• LABORT
A unit that is sending a bit on the bus also monitors the bus. A LIN bit error will be flagged
when the bit value that is monitored is different from the bit value that is sent. After
detection of a LIN bit error the transmission is aborted.
A LIN checksum error will be flagged if the inverted modulo-256 sum of all received data
bytes (and the protected identifier in LIN 2.1) added to the checksum does not result in
0xFF.
A LIN parity error in the IDENTIFIER field will be flagged if the value of the parity bits does
not match with the identifier value. (See LP[1:0] bits in
Identifier Register” on page
corrupted parity bits and a corrupted identifier. The hardware does not undertake any
correction. However, the LIN slave application has to solve this as:
- known identifier (parity bits corrupted),
- or corrupted identifier to be ignored,
- or new identifier.
A LIN synchronization error will be flagged if a slave detects the edges of the SYNCH field
outside the given tolerance.
A framing error will be flagged if dominant STOP bit is sampled.
Same function in UART mode.
A time-out error will be flagged if the MESSAGE frame is not fully completed within the
maximum length T
IDENTIFIER fields (see
Overrun error will be flagged if a new command (other than LIN Abort) is entered while
‘Busy signal’ is present.
In UART mode, an overrun error will be flagged if a received byte overwrites the byte
stored in the serial input buffer.
LIN abort transfer reflects a previous LIN Abort command (LCMD[2:0] = 000) while ‘Busy
signal’ is present.
