21.3.3.5 LIN Control Register (ESCIx_LCR)
ESCIx_LCR can be written only when there are no ongoing transmissions.
19 STO Slave time out. Represents a NO_RESPONSE_ERROR. This is set if a slave does not
complete a frame within the specified maximum frame length. For LIN 1.3 the following
formula is used:
20 PBERR Physical bus error. No valid message can be generated on the bus. This is set if, after
the start of a byte transmission, the input remains unchanged for 31 RT clock cycles.
This will reset the LIN FSM.
21 CERR CRC error. The CRC pattern received with an extended frame was not correct.
0 No error
1 CRC error
22 CKERR Checksum error. Checksum error on a received frame.
23 FRC Frame complete. LIN frame completely transmitted. All LIN data bytes received.
24–30 — Reserved.
31 OVFL ESCIx_LRR overflow. The LIN receive register has not been read before a new data
byte, CRC, or checksum byte has been received from the LIN bus. Set when the
condition is detected, and cleared by writing 1 to it.
