The LIN-UART operates in four different modes. The operating mode is selected by the MD0
and MD1 bits in the LIN-UART serial mode register (SMR). Operating mode 0 and operating
mode 2 are used for bi-directional serial communication; operating mode 1 for master/slave
communication; and operating mode 3 for LIN master/slave communication.

Operating mode
0 Normal mode
1 Multiprocessor mode 7 bits or 8 bits +1
2 Normal mode
3 LIN mode
- : Unavailable
* : "+1" is the address/data select bit (AD) used for communication control in multiprocessor mode.
The MD0 and MD1 bits in the LIN-UART serial mode register (SMR) are used to select the
following LIN-UART operating modes.

MD1
• Operating mode 1 supports both master and slave operation for the multiprocessor mode.
• The communication format of operating mode 3 is fixed: 8-bit data, no parity, stop bit 1,
LSB-first.
