5.9.3

Universal asynchronous receiver/transmitter with LIN support

(LINUART)

The devices covered by this datasheet contain one LINUART interface. The interface is

available on all the supported packages. The LINUART is an asynchronous serial

communication interface which supports extensive LIN functions tailored for LIN slave

applications. In LIN mode it is compliant to the LIN standards rev 1.2 to rev 2.2.

Detailed feature list:

LIN mode

Master mode:

•

LIN break and delimiter generation

•

LIN break and delimiter detection with separate flag and interrupt source for read back

checking.

Slave mode:

•

Autonomous header handling – one single interrupt per valid header

•

Mute mode to filter responses

•

Identifier parity error checking

•

LIN automatic resynchronization, allowing operation with internal RC oscillator (HSI)

clock source

•

Break detection at any time, even during a byte reception

•

Header errors detection:

–

Delimiter too short

–

Synch field error

–

Deviation error (if automatic resynchronization is enabled)

–

Framing error in synch field or identifier field

–

Header time-out
