13.4
LINUART interface
13.4.1
Framing error issue with data byte 0x00
Description
If the LINUART interface is configured in LIN slave mode, and the active mode with break
detection threshold set to 11 (LBDL bit of UART_CR4 register set to 1), FE and RXNE flags
are not set to 0x00 when receiving a data byte with a framing error, followed by a recessive
state. This occurs only if the dominant state length is in between 9.56 and 10.56 bit times
the baud rate.
Workaround
The LIN driver software can handle this exceptional case by implementing frame timeouts to
comply with the LIN standard. This method has been implemented in ST LIN 2.1 driver
package which passed the LIN compliance tests.
13.4.2
Framing error when receiving an identifier (ID)
Description
If an ID framing error occurs when the LINUART is in active mode, both LHE and LHDF
flags are set at the end of the LIN header with ID framing error.
Workaround
The LIN software driver can handle this case by checking both LHE and LHDF flags upon
header reception.
13.4.3
Parity error issue when receiving an identifier (ID)
Description
If an ID parity occurs, the LINUART wakes up from mute mode and both LHE and LHDF
flags are set at the end of the LIN header with parity error. The PE flag is also set.
Workaround
The LIN software driver can handle this case by checking all the flags upon header
reception.
13.4.4
OR flag not correctly set in LIN master mode
Description
When the LINUART operates in master mode, the OR flag is not set if an overrun condition
occurs.
Workaround
The LIN software driver can detect this case through a LIN protocol error.
