13.3
USART Interface
13.3.1
Parity error flag (PE) not correctly set when overrun condition occurs
Description
If an overrun condition occurs, the parity error flag (PE) of the UART_SR register is not set
for the frame which caused the overrun condition. The PE flag represents the status of the
last correctly received frame.
Workaround
None.
13.4
LINUART interface
13.4.1
Framing error with data byte 0x00
Description
If the LINUART interface is configured in LIN slave mode, and the active mode with break
detection length is set to 11 (LBDL bit of UART_CR4 register set to 1), FE and RXNE flags
are not set when receiving a 0x00 data byte with a framing error, followed by a recessive
state. This occurs only if the dominant state length is between 9.56 and 10.56 times the
baud rate.
Workaround
The LIN software driver 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 when receiving an identifier (ID)
Description
If an ID parity error occurs, the LINUART wakes up from mute mode and both LHE and
LHDF are set at the end of the LIN header with parity error. The PE flag is also set.
